NewPipe also lets you export your subscriptions (which is just a bunch of links to RSS feeds), so you aren't shackled to Android/RSS.
YouTube does make some kind of changes significantly harder to build than simple scripting will handle though. I do definitely see some reasons for specialized apps, and video is a fairly prime example of where they're often more capable or more (power/time/whatever) efficient.
When I switched over to using an app, there was also a good chance that an algorithmically suggested video from an unfamiliar creator would capture my imagination. When I have looked at recommendations recently, I doubt that would be a problem today. Too much AI and human generated slop. Too many click-bait titles that barely give a hint on what the video is about, never mind why I should care about their take on it.
Then there are the days when I am both bored and exhausted. While I don't tend to watch much on those days, I have known myself to scroll through the recommendations to see if there is anything to occupy the time.
The block in degooglifying is usually region not lack of willingness. Some places are locked to Google by no fault of the consumer.
This has worked flawlessly for me on every phone I've used.
but for some reason google knows better and there is no efficient way to run local containerized web services.
Your comment made me try Firefox for the Nth time right now.
And the rendering is still bad like I remembered it. Download the image locally and open it in an image viewer so you actually view the pixels 1:1, then see if you can tell which one is Firefox (I can): https://imgur.com/a/FsXuoa3
I'm staying with Chrome.
But hey, if there's one thing that's definitely going to convince people to do things they don't like, it's to diminish their grievances and guilt-trip them.
