So others know where to find you - there's a bunch of tools for that, but unless you use the same one it doesn't work. Can't think of a more efficient way personally. Though I don't think anyone needs to be obnoxious about it with series of tweets and stuff.
It's a lot harder to decentralize when you have decentralized tools...
There's some corollary here to the law of momentum that allows social networks to become juggernauts. It probably applies to repressive governments as well. Maybe: The more entrenched the system is, the more you have to use the system's own tooling to get people to escape it?
I wasn't referring to anything in the article or about including your Mastodon handle in your user name or description. Some people though keep tweeting how they "left Twitter", cross post content etc. I find that a wee bit obnoxious - but since I don't really use Twitter anymore it doesn't bother me, I could just understand someone wanting to take action based on it.
