It is a stampede:

"Minnesota Public Radio has joined the growing number of public radio stations that are quitting Twitter.

'After much discussion, we concluded that continued use of the social media platform Twitter by our organization was contrary to our mission and core values..Instead of being a neutral and efficient channel for serving the public, Twitter is now actively aiming to undermine the integrity of public media organizations like ours.'"

Minnesota Public Radio to quit Twitter

The move comes after National Public Radio and the Public Broadcasting System both announced plans to leave the controversial social media site.

@tchambers Good. Fuck Twitter and fuck Twitter in unison.
@tchambers I got the American Public Media email to donors (APM is just the national distribution brand name for MPR—they’re one and the same company) and then, a few hours later, one from Colorado Public Radio. Good for them both, and also for NPR.
@tchambers I hope that more news organizations and radio stations join existing Mastodon instances or create their own Mastodon instances.
