Sounds like the right should start creating their own social media platforms to compete,

Won't work. All new platforms have the same problem. The minute they hit a certain size and influence level the admin sells out the company to tech oligarchs who start banning people. Saidit has already isolated this sub and they haven't even sold out yet.

One solution is right wingers getting into public spaces more (which they anticipated and created a fake pandemic to counteract). Another solution is a crypto based social media site run outside of the US that is owned and controlled in a decentralized way. Decentralized crypto currency exchanges are becoming a thing and decentralized social media sites can do they same. We need an anti fragile attitude and an anti fragile site. The torrent community is a good example of anti fragility. Look at how The Pirate Bay continues to operate despite constant attacks.
