It's been an interesting read and I agree with both sides, having both worked in the media and also retail you also see the story from a broader point of view.
Both Freesat and Freeview having licences lasting to 2030 (maybe 2035) where the government will review them, I know recently some broadcasters renewed their capacity deal with SES who operate the Astra satellite which feeds the Sky/Freesat channels. I know the commercial channels also renewed their contract with Arqiva who operate the terrestrial transmitter network, so it's going to be here to stay for a while yet.
For the broadcasters, TV and radio still makes a lot of money, advertisers are still spending with them and want to broadcast more ads (a recent review stopped this from happening) the linear outlets are still popular with younger age groups and I'm still amazed how many people just "want" Freeview.
I think the mobile providers are more focused on getting their 5G sorted (you also forget that a lot of the Freeview transmitter network host mobile cells as well) and I believe mmWave is up next for auction in the UK.
The main problem is (as always) awareness, even with all the MVNO providers we have, most customers in my last shop still only knew the four legacy providers, the same goes for streaming services, some were convinced BBC programmes came from Netflix.
In niche areas of the internet, like this forum or other big mobile forums, the need for Freeview/Freesat linear and non-demand content may not be needed but "most" people aren't us, some don't even know what FTTP is, even my colleagues in the media or the shop!
The time will come, but it's going to be a longer transition than we all think.
As for the privacy argument, that ship sailed ages ago, if you think having a SMART TV is bad, you've already signed up for this forum, have a mobile and done much more by shopping online etc etc, you can take steps but most of us aren't as privacy savvy as we'd like to think we are.
