We all know Mastodon has flaws. But whatever flaws Mastodon has, it still fixes a fundamental flaw with Twitter: one asshole can disrupt service at Twitter, while Mastodon’s service can’t be disrupted due to it being decentralized.
Now don’t get me wrong. Individual admins on specific Mastodon servers can be asshole who disrupt service. We have seen this happen.
But due to Mastodon’s decentralization, asshole behaviour of server admins has limited impact. If you don’t like your asshole admin, you can easily migrate your account elsewhere to a better, nicer server.
Think of decentralization as an “asshole limiter”. Twitter has no asshole limiter. Mastodon does.
