"Protests against tech giants and their impact on the San Francisco Bay Area economy just got personal. According to an anonymous submission on local news site Indybay, an unknown group of protesters targeted a Google engineer best known for helping to develop the company's self-driving car. ... The protest against Levandowski came the same day that the San Francisco Municipal Transit Authority (SFMTA) voted for the first time to take action regulating Google, Facebook, Apple, and a number of other large tech companies that shuttle workers in private, Wi-Fi-enabled buses from the Bay Area to points south in Silicon Valley."
