No manager dares to refuse these initiatives because they'll be instantly named by the activist, with the help of journalist friends, and ensure they lose their job.
Hence by going one at a time, a small group of activists can change far larger organisations.
Of course, every action has a reaction. Enough resentment has built up, that made anti-woke a legitimate position to take in the public eye, with no longer much risk of losing the job. This makes all the previous tactics lose their power.
Also, the 'anti-woke' crowd is learning these tactics too. From congressional grilling of university presidents, to gamers explicitly documenting the DEI consultancy involvements, its all targeting and absolutely destroying individuals to cause a chilling effect on the populace at large.
