It's nice that you can unlock the bootloader on these and flash Lineage if you want to limit snooping by Google.
That being said, I think that you get more flexibility and performance with a mini PC and and air mouse. For one, stock (Googled) Android does not give you an easy way to use a browser with an ad-blocker, which is still the best way to stream from many sources without ads. Also all these anemic Android boxes struggle with high bitrate 4K videos.
At this point I actually don’t know why I bother with the streaming services anymore. I recently watched a blu ray movie after a long time of just watching streams and the quality of the picture just blew me away.
Is there even Blu-ray level content available for series that are streaming only? Or is it restricted to just movie releases?
Edit: actually, now that I think of it, having the audio available in our local language instead of English is a boon for the kids. But otherwise, I don’t know why we bother.
You unfortunately lose Widevine support when you do this though (either switching to LineageOS or a mini-PC). That means you can't stream any of the mainstream services in anything like a half-decent quality.
It's very unfortunate that every streaming service has given up on supporting anything except Google-fied Android and Apple iOS/tvOS. I dont like the services to begin with, but a fully Jellyfin stack can only get you so far when there are niche requests involved as well.
