It turns out that tech companies were key to prevent the "Detroit-ification" of San Francisco. Tech companies mixed local drug users, deadbeats, and shady/violent people with Stanford, Cal, MIT, Caltech graduates and generally people who contribute to society. This made the city much wealthier and safer. As a native San Franciso citizen, I welcomed the change.
If you browsed /r/sanfrancisco in 2016, you would have seen how anti-tech everyone was. The users there were convinced that tech companies made the city worse. Now what? Where are those people now? I bet most of them left the city after realizing that the safety and money tech brought is now gone. Isn't this what they wanted?
