I either get down voted or ignored for this... But you should check out beeper. It's just matrix with bridges but makes the login procedure much easier for normies as it's an email two way auth vs maintaining a key and password....
I tried revolt and... It sucks. None of my friends are on revolt. None of my bots work on revolt. Same with matrix. Matrix is horrible for large communities where discord offers inheritable permissions, forum channels, channels that only some users can see, its just not the same use case at all.
Also please link the original YouTube link. I don't like invidious, I have my own preferred frontend. Don't force people to use the frontend that you like. I use freetube, which is just as private and better for my needs. But I can't automatically open freetube if you don't link the original YouTube link. Same with people who use literally any other frontend than invidious.
You can use Libredirect, an extension that redirects you to privacy-respecting alternatives to websites, and update it in the settings to make it automatically open in Freetube. https://addons.mozilla.org/en-US/firefox/addon/libredirect/
I use LibRedirect. It can handle youtube links and redirect them to a number of frontends. It can also directly open freetube. It's a firefox extension.
I'm still keeping up the Invidious link since exactly in the Privacy community rules, it says that there can't be any links with any major tracking requests on it. You can easily just change the link yourself if that's the case.
If none of your friends are on revolt or matrix, that's an issue on your end. You can just make your own rules and ask people to contact you on only private platforms or via email. Which is exactly what I've done when I was migrating from Discord to Revolt.
However, if you absolutely have to use Discord, which I wouldn't recommend, the least you could do is disable the diagnostics and only use it in a private browser or a open source client like Datcord or Spacebarchat.
I run a large community, it’s not just a matter of asking people to contact me elsewhere. You can’t uproot a community and bring it somewhere else, and I wouldn’t be able to at all because of matrix’s and revolt’s lack of permissions systems, bots, and other things that are unique to discord. I would welcome a viable alternative. I’ve spent many hours trying to make matrix work with the functionality I need, and it’s simply not possible.
As far as the link goes, I’m not sure if those rules mean the links themselves must not contain tracking, or that the website on the other end must not contain tracking. You can have youtube links that themselves have no tracking information in it. You can’t just ban links to any site with tracking, you’d just have nothing you can link to.
Edit: the rule also says "isn't great". That's not the same as "isn't allowed". Forcing someone onto a frontend that either doesn't work for them or is annoying to use I think is worse than letting users redirect themselves using a "tracking filled website" link.
