Quick shout-out to Grayjay: An app to watch videos on any platform - reducing the power of individual services. The Software is open-source and can be found here: https://gitlab.futo.org/videostreaming/grayjay
I will test this out for myself and hope someone here finds this useful.
App looks legitimately amazing. Seems a bit buggy in alpha but I'm sure it'll be ironed out. I just hope they look into supporting Piped instead of directly connecting to YouTube, as well as SponsorBlock. Once they get those 2 things and iron out some of the bugs, I'll primarily use it for sure. Its a great concept.
