As a Xoogler who just wanted to get on topic product updates ( and Sergey jokes I guess - he really is insanely funny), I actually found it frustrating that it was an overloaded forum for any and all random topics.
Were I working there, this would have made sense to me.
I didn't work there to be an activist. I worked there to go work on products.
I don't get other comments that say "courted activists". The recruiting pitch is about impact, a good work environment, compensation and interesting products.
