Googlers, by far more left than most of the country, cannot fathom that they are part of "the rich" most of them rail against. Some of these people are getting kicked out of their apartment, can't find a new place that's anywhere near their job, so they're getting kicked out, forced to move away, forced to quit their job and sent packing to nowhere with no job, no roof over their heads and no money. Plenty of these will be homeless for a while to come.
My opinion is : stop fighting this discussion. You can't win. There are no words anywhere that will make people accept being forced into homelessness without fighting. Just shut up, go to church sunday and pay a few hundred bucks on collection, because that will actually help them for a while. Lots of churches help people relocate because they've got lots of locations, and this is (part of) what they do.
TLDR: These protesters are right. Google, or googlers, techies in general, are forcing the lower rungs on the social ladder into homelessness.
Sorry to say, but you're lucky you're in America. In Europe, I cannot imagine these protests would have remained peaceful. A few tires and one window does not count as violence. Visit the poor parts of Brussels once with what a techie normally walks around with in San Francisco and you'll know what violence is.
Of course the reason this doesn't happen in Sanfran is that this is just the n-th time the poorest are being forced out.
