Maybe not, but I still see it in the same general category as a boycott, because: if nothing illegal is actually going on, then what can anyone do to stop it, except impose authoritarian restrictions on free speech? If the company/institution wants to ignore people, fine, but they’ll have to deal with the consequences. (If those consequences are personal, e.g. death threats, then those should be nipped in the bud. But my feeling is that they’re usually financial or reputational.)
