This is changing; Facebook is sponsoring 1500 units, 300 affordable, in Menlo Park, Mountain View also becoming more welcoming of new housing, they recently approved 10,000 units in the North Bayshore area. Cupertino (where Apple is located) continues to distinguish itself in a bad way; they approved 11,000 new office spaces for Apple without any corresponding increase in housing, and routinely send people to San Jose city council meetings in an attempt to block housing on San Jose land.

Again, there are promising developments here. Facebook sponsored a Dumbarton Corridor study, and all of the tech companies are throwing their money behind a new bridge tax ballot measure that would raise money for public transit. http://www.greencaltrain.com/2017/08/dumbarton-corridor-stud...
