That's what this is about. Sarah Mei is coming from a place of, "Because RMS said this Very Bad Thing, no one should associate with him at all." Carrying with it an implied threat: if you continue to associate with a Bad Person, then you are a Bad Person and maybe whoever signs your checks should know just what a Bad Person you are.
I have no horse in this race, this is too much of a hot topic to take a stance about personally, but I can't say I'm enjoying the modern viral Twitter shit-storm phenomenon very much.
The loudest campaign, wrong or right, wins by deafening everybody and amplifying their moral stance through that platform.
I have nothing against Mei personally, but I _loathe_ the modern Twitter driven moralism. Does everything have to be a crusade?
Sure, but others are entitled to tell him he should step down, and he's entitled to do so if he feels like it.
Political changes tend to follow behind cultural changes here. If this cultural change has legs, then I have to wonder how long it will be before the Government does start acting more directly against anyone who has views outside of the mainstream. Social Credit score, anyone?
Government Social Credit Scores are bad. It does not follow that people don't have reputations.
