I tried using Peertube but finding an instance whose content policy fits what you're meaning to upload and responds to sign-up requests isn't trivial. It's basically perpetual storage they're offering for free so I get it, maybe the real surprise is that youtube makes so much money off of us that they can afford this

Found one in the end when I didn't have a choice anymore and put renewed effort into it (Google's algorithm won't let me into my account anymore, saying they don't have enough information to verify it's me (username, password, recovery email.. not enough apparently, but there is nothing else), so I'm a Peertube exclusive now) but iirc I can't use it for everything, like if I wanted to upload something in Dutch I'd have to find a new server that allows my language
