@aral chiming in with my 2 cents because I literally jumped into a discussion like this back when gab switched to Mastodon.
back then I was against Tusky hardcoding a block to gab, instead allowing people to block the instance at their will.
I sent an email to RMS, which told me, blocking gab doesn't change the status of free software.
so tell me, how blocking certain hashtags, specifically political ones, goes against FREE and LIBRE?
