FSF is Now on Bluesky - But Won't Advocate Signing Up Due to Nonfree JavaScript

The Free Software Foundation (FSF) is now on Bluesky, they announced this week. But "We can't advocate that you sign up for a Bluesky account like we do with Mastodon or PeerTube since signing up for Bluesky means loading the registration page's nonfree JavaScript..." While federated, Bluesky is generally not considered part of the "fediverse"...
