In fact the buses weren't even really the problem. The protests were largely about rent increases caused by tech workers. The buses were just a symbol of the difference between tech workers and everyone else (and broad inequality).
Plus I struggle to side with the protesters when they do stuff like this[0]:
> Last week, a group of activists stalked a Google engineer at his East Bay house, urging the masses to “Fight evil. Join the revolution.” [..] The group that stalked Anthony Levandowski, an engineer at Google X, the company’s clandestine research laboratory, calls itself the Counterforce, after a Thomas Pynchon novel. About a dozen members, all dressed in black, gathered outside the Berkeley house where Mr. Levandowski lives with his partner and two young children.
> They unfurled a banner and handed out fliers detailing the engineer’s work on Google’s driverless car technology, Street View and Google Maps. The flier read: “Anthony Levandowski is building an unconscionable world of surveillance, control and automation. He is also your neighbor.”
That's pretty messed up. The dude was a random employee, with a family...
