I'm honestly surprised that somebody hasn't sold a bundle of a TV antenna, set-top box, and cloud storage for a DIY streaming service kind of thing. I'm aware of Plex and Jellyfin, but I feel like you could make the setup instant and painless even for non-technical users. All these problems we're seeing with streaming (content spread over many expensive subscriptions, unregulated advertising, disappearing/moving content) would be easily solved.
In Italy such devices are known as Pezzotto, because they are like a patch to connect to different streaming, IPTV, etc channels. Of course illegaly.
There was a huge crackdown of both such services providers and their users in the EU (ties between politicians and sports broadcasting lobbies), which was immediately followed with increased pricing from every service, from Sky, DAZN, Mediaset Premium etc to on-demand platforms like Prime, Netflix, Disney Plus, etc.
In addition it seems a cartel has followed up: almost every service has added Ads on top of their lower tier, even though users already paid the increased price in service.
Plex, as a business, is already in a tough spot because it's mostly used to stream pirated media, and if they make too many overt moves towards making piracy easier, media companies might start going after them.
Thus all the stuff to haphazardly integrate streaming services. Selling it as a preconfigured kit might be risky.
