I love mastodon and I'm pretty sure I won't be back on Twitter, the biggest problem I find so far is that most of the people I see on the platform have the same ideological orientation as me. For now, people who do not live by the same principles and ideals as many of those here will continue to use Twitter, even if many of these people were concerned about censorship. And it is paradoxical because there is no better option than decentralization to avoid censorship.
And ofc I still think most people won't migrate here because it's not as intuitive to use as Twitter or people don't even know about the platform, this is the case for the Spanish-speaking community.
