This lacks nuance. You ignore the effect they have on the ecosystem as a whole. Mentioning the "Go community" and their "agreement" of Google's decisions without acknowledging this is disingenuous at best. They have already swayed and gatekept large swaths of the (web)development "community" by their decade-long dominance and no one can make an impactful, meaningful decision in that field without their implicit approval. Their dominance is felt best by the way they control the conversation i.e. what we don't talk about - i.e. the web among other things they touch sucks, continues to suck and it is going to get worse and less free and they are significant negative contributers. So yeah, I'd rather see them cut into pieces.
