While watching the video I couldn't stop thinking about the fediverse. It's basically self-organized social-media. While it is far from perfect it is so much better than the corporate alternative in terms of relevant content. I'm just sad that basically nobody I know personally actually uses the fediverse...
If you want to get people to join the fediverse, I think the best way is to point out where it shines, not necessarily in relation to other social media. I've gotten a couple of friends to sign up for Lemmy because of how trans-friendly it is, especially on Blåhaj Zone. It's such a breath of fresh air from the rampant transphobia on mainstream social media platforms.
The ui/ux also needs a lot of improvement but trying telling a FOSS/Linux advocate that and they’ll call you stupid and say if you cant install arch you shouldnt be using computers or something of that sort.
