It's not like we can plead with Exxon or Disney to switch off Twitter.
But governments? Three levels of government in most countries all use Twitter on a low, department level. Every paving job, every snow day is announced on Twitter. All the Universities and schools announce on Twitter.
Lean on THEM. If all government and academia leave Twitter for Mastodon, big blow for freedom right there, big blow against a gross site.
And it might start a stampede.
