The first two paragraphs: you are me. The last one: I don't think about upgrading because my TV is off all the time. I watch it on a tablet or on my phone. I use a Raspberry with a TV hat to stream free to air TV on my home network and apps for the IP based content. My TV is the backup device.

About the subject of this thread, too many paid streaming services are maybe too inconvenient. If they are, the market will fix that. That is: some of them won't make enough money and close, or sell to a competitor, or just create content and license it to streaming services.

My preference would be not to pay per month but per view. There are months when I don't watch any series and months when there is something I like. About movies, maybe no movie at all for a year or two, then a few of interesting ones, including old ones that I never watched and I feel like to watch. The last one was Gilda, 1948.

Yeah, same issue. Though I use Raspberry Pi as a backup when the playback doesn't work (it's not just H265, though others formats failing to work on the TV happens much more rarely).
