It's not really a strawman to say that shuttles take cars off the road because Googlers commuted from the city to Silicon Valley by car before the shuttle program existed. In fact, it started as a 20% project in response to the annoying commute.
But oh, I forget, this fits right in with Google's approach to doing business, from whether it's scanning books or slurping up wifi data: break laws first, deal with consequences later.
Are are you harping on about where the busses are parking? If so, why not direct your irritation at the city government, which could be making a few hundred extra dollars a week writing them parking tickets.
Doesn't make it right for the protesters, and guess what, it doesn't make it right for Google to keep on doing what they're doing.
