I think lots of people are uncomfortable with language being changed in a top-down way by people who aren't particularly democratically accountable more than anything.

To be honest I'm not sure where I stand on prescriptivism as a concept. If there's a genuine organic demand (as opposed to corporate PR people playing tokenism) for it in the context of tackling racism then fair enough I can get behind that, but I don't really like the idea of language itself being used as a political cudgel to beat your opponents with. The word Orwellian is relentlessly misused these days but I think if we are going to forcefully change language it needs to be something done with great consideration and democratic oversight to avoid this tool being wielded abusively. For example, I'd love to abolish all Americanisms from British English which is exactly why I'd be grossly unfit for such a language-defining duty!
