That’s a very good point. As I mentioned in my previous comment, I haven’t followed the situation (or other Google situations like the ones you mentioned) closely. However, I feel a just-as-reasonable explanation is that Google did those things to save face because if they truly felt those were the right things to do, there would be no retaliation and there would be an implicit agreement that the intention was morally motivated and not intended rabble-rousery.
On the other hand if the situations you mentioned are unrelated to the Women’s March, which it seems they are, then I really don’t see them as being relevant to whether or not the people in question were rabble rousers. Protestors are not a constant set of people and each protest and the organizers of said protest have to be looked at individually, at least in terms of determining whether 1. or 2. is most reasonable.
Otherwise, it’s a broad generalization of “protestors”, which would inadvertently make 2. the more reasonable narrative as well because 1. would be moot to the specifics of the particular situation.
