It's funny. I have previously compared the DVB hardware market in Europe and the Middle East to the early GSM phone market. In both cases, there was a vibrant market for hardware variety, manufacturer, and feature set over there, because the carriers hadn't tightly coupled the hardware to the user service account. Here in the U.S., it was years before anyone knew what a SIM card was, and users were able to swap them between phones.
The lack of diversity in downlink providers is probably the root of this. You have 2 carriers, one who, for years, only used the barest feature set of DVB-S and wound up forking their protocols into weird modulation schemes. (D!SH), and one that had a protocol that pre-dated the gelling of the actual DVB-S standard (DirecTV). In Europe, people were buying CAMs and cards from several different providers and popping them into CI slots as they saw fit, essentially creating their own "bundles." That was because the broadcasters used an actual standard.
The other thing that one can't ignore is that the case that, for a time, was the largest lawsuit in the world. It was squarely around issues of conditional access, efforts to subvert it, and worst of all, between those same two U.S. carriers. If you want a wild ride, read the book "Murdoch's Pirates." I swear, you won't believe what you're reading, but a lot of what's in there is provable historical fact.
(If you don't know the story of the suit involving DirecTV/News Datacom-NDS/D!SH/Nagravision-Nagra Kudelski, it reads like a movie script, but it really happened.)
I got motivated by subscribing to the now-defunct Tele-Satellit(e) magazine, published by "Dr. Dish" in Germany. I would highly encourage people to peruse their now open and free complete issue archive online. The ads for receivers alone will make anyone in the U.S. feel as though they are living in a country that doesn't have electricity or running water.
I originally bought my first Dreambox from a Canadian retailer at a time when it was virtually impossible to find FTA receivers in the U.S. Unbeknownst to me, he may have been involved in what was then a thriving black market for gear that let Canadians watch U.S. DBS services without paying, and got in some trouble. I am pretty sure the RCMP got his customer list. I wasn't worried. Later, I actually was a paying subscriber of Canadian satellite TV because the picture quality was better than anything I could get with D!SH or DirecTV, and some of the news and science fiction was way more interesting than anything on cable/fiber here in the U.S.
There absolutely has been a migration to IPTV/"OTT" services, in that even my friends who have worked at large cable companies have been testing IP delivery of their whole linear channel list. I don't know that we'll ever completely see Ku-/Ka-band services vanish though. I don't know whether AT&T is still uplinking their HITS (Headend-In-The-Sky) service for rural customers, but I think it might still be out there, and some of the niche foreign and religious programmers are still depending on it.
Personally, I think we have to see how the confluence of several things shakes out. I can't say I've exhaustively thought this through, but I've done market analysis for a living before, and there are the things that stick out to me:
1 - The FCC just auctioned off a big chunk of what used to be C-band spectrum, presumably for use with LTE/5G wireless services. I don't know what that will do to the price of Ku-band transponder time.
2 - Starlink, if it continues to work as described, will provide reasonable IP service to people who previously only had tin cans and a wet piece of string, dial-up, crappy DSL, or Wildblue/Gilat/Hughes for Internet service. Pretty much none of those are up to the task of delivering one 4K TV stream, much less more than one. Starlink beta users are consistently reporting 80-140Mbits/sec at 23-40ms latency. That would do fine for streaming 4K video IF
and only if, the jitter (variability in latency) isn't too wacky. I have yet to hear much from people trying it for VOIP, for example, but time will tell. I don't know what effect Starlink may have on Ku-band transponder time, either.
3 - It remains to be seen what the new administration's FCC will look like in terms of leadership and initiatives.
4 - I think there will always be some audience of narrowcasters who like the idea of satellite delivery of their services. Just look at all of the audio-only downlinks on Galaxy 19. It's not all international content.
5 - There are long time lags between technology changes and adoption by radio/TV broadcasters. We're only now starting to get services in the U.S. that are experimenting with DRM (Digital Radio Mondiale), a digital shortwave format.
6 - ATSC 3.0 has some wacky features that could be really interesting in terms of providing content that makes Internet add-ons to regular programming pretty easy to do. (I won't talk about the potential security nightmare that comes from transmitting a signal that makes people's TV's silently fetch URLs in the background from wherever you want, but you can imagine it.)
The discussion of crowdfunding gear is interesting to me. As someone who has and occasionally still does work in the traditional startup funding world, the number of things I've acquired recently from crowdfunded hardware markets like Crowd Supply and Tindie, gives me faith that if we really want a better receiver, there is a path to it.
I don't want to crack-shame, but as someone who has used a DiSEqC rotor for over a decade, it has disappointed me to see just how many people only wanted to point dishes at the "big 2" in North America and avoid paying their bill, as opposed to really exploring the craziness that is out there in terms of both wild feeds and international content, not to mention weird data services. It even shows in the comparative immaturity of the codebases for motor control in various Enigma/Enigma2 distributions over the years. (People still don't believe me when I describe some of the insanity I recorded during the Gulf War, and that I've watched TV show hosts talk trash about their own programs when they weren't "live" but were live.)
