Here is a recent video commentating about the deplatforming on Gab.ai : https://www.youtube.com/watch?v=roShIETIEk0 .
While Gab.Ai's mission for free speech is admirable i actually think Mastodon is a better solution. Because it is federated and every instance can have there own rules its not at risk of being taken down as a whole and people can join an instance they like.
I hope Mastodon gets more attention in the alt-media because as far as i see it mstdn.io is the superior Twitter alternative.
The social network of the future: No ads, no corporate surveillance, ethical design, and decentralization! Own your data with Mastodon!
