I used to work in tech in the Bay Area. I stopped wearing company-branded clothing in San Francisco circa 2015 when anti-techie protestors picketed company bus stops [0], picketed the homes of Google employees [1], assaulted people wearing Google Glass in the street [2], and shot out commuter bus windows on the freeway [3]. Company merch just attracted the wrong kind of attention. The situation was getting bad then, sounds like it’s only gotten worse with the election.
