If it’s a question that has no answer (or no useful answer) it’s totally fine to comment with an answer.
I figure that someone will eventually stumble across the same thread that I did if they have a similar question. Might as well contribute and share some knowledge.
It’s not an easy answer, but the best way I’ve found so far is to use GrayJay.
If I find that one of the content creators I follow on YouTube happen to post their content on any other platform, I switch my subscription to that platform.
Besides YouTube they support Nebula, Twitch, Odysee, PeerTube, Dailymotion, Bitchute, Kick, BiliBili, Rumble, Patreon, and more.
If this is something we actually want to fix, we’ll need to work with legislators to come up with a law that can’t be worked around by using some Terms of Service that everyone magically agrees to by visiting a site.
A lot of people claim that this was done illegally, but artists really shouldn’t be using websites like Instagram where they grant a royalty-free license to Meta where they are allowed to sell your images to anyone they want.

when you share, post, or upload content that is covered by intellectual property rights (like photos or videos) on or in connection with our Service, you hereby grant to us a non-exclusive, royalty-free, transferable, sub-licensable, worldwide license to host, use, distribute, modify, run, copy, publicly perform or display, translate, and create derivative works of your content (consistent with your privacy and application settings).
One of the best ways to start getting away from YouTube is to use Grayjay.
You can still follow content creators who are only on YouTube, but it allows you to curate your feed and mix in all of the content creators that do upload their content to other platforms like Peertube, Nebula, Odysee, Patreon, Twitch, Kick, Bitchute, Rumble, etc.
