unfortunately this makes your content pretty hidden. You are not within youtube's search anymore, you're not in any sidebar as related video either
Own your own content, but if you seek to spread a message you might want to use closed proprietary ecosystems as long as you aren't dependent on them.
For example, I was recently updating linkedin, and went to add Bruce Schneier, but he had a post that said he never checks or uses it and only links to his website from there. He still has a presence there though, and that really hit me how much these little walled gardens we let take over so much of our compute ecosystem are starting to look like prison, even for your standard copyleft hating SV hipster.
Of course Stallman would say don't even use them, and he makes some good points, but the problem we have now is even if you have a good message you can't reach the masses without going through some priestly gatekeeper of the government-corporate media power. So you have to use the system to beat the system.
Upload to as many sites as possible, link between them. Keep offline copies if you can.
Which by the way is what RMS did back when the GNU system didn't exist: use proprietary UNIX to develop GNU, replace the system piecemeal.
In Stallman's case there were no free software OSes. One could not use a computer in freedom. Therefore he used a nonfree OS to write free software until he could run a free software OS and thus had no more need for nonfree OSes. For years now he (and the FSF) don't run nonfree systems. They even endorse computers (and other computer hardware) that can be run completely in freedom (see https://www.fsf.org/ryf for details).
We already have file hosting options that don't use DRM, nonfree JS (or indeed any JS), and avoid the other problems of YouTube. There's no need for coming up with something new as we already have viable other means of sharing files.
We don't need YouTube, they need us. By buying into their limitations and restrictions uploaders endorse YouTube (which is undesirable and certainly not very thoughtful) and help foist YouTube's choices on others (which is unethical).
I'm all for getting rid of YouTube, but I'm not sure how we should do it.
