Vivian (they/them)

I use an app called Moshidon, it’s a fork of (a fork of) the official app, it’s quite nice

Completely switched to Mastodon and here, I’d rather not use platforms that are locked down by corporations and will inevitably enshittify without leaving me a simple way to migrate

Yeah, you subscribe to hashtags to start, find people you agree with/find interesting, follow them, and then as they boost stuff you’ll find more and more people to follow.

I love that I managed to guess quite a few of these

The way I understand it is that they can relicense it and then publish it if they want, but the GPL would still fully apply to the previous versions.

The first question you cited seems to refer to any different organisation/individual making changes to the source code. And the second seems to refer to revoking the GPL for an already released version, which they would of course not be allowed to do.

This would make sense as ownership of the copyright would supersede a license.
