And it wasn't just extremist groups saying insane shit on TikTok. People were getting harassed through GitHub, issues were being brigaded, tons of big FOSS projects had some big CoC kerfuffle, then there were the master/slave, git master branch, whitelist/blacklist naming things, demanding renaming of projects, demanding people be fired, etc. Some of these things were reasonable, some were unreasonable, but it's incredibly disingenuous to pretend that it was just "One extremist group says insane shit on TikTok". It was a lot of people effecting a lot of real changes. Notably in FOSS, it was a lot of outsiders coming into a space and telling the people in that space how they were supposed to do their jobs, despite the outsiders not contributing anything other than judgement and not having any stake in it.
I definitely see some parallels, even if they aren't equivalent.
