We are having a really bad housing crisis in coastal cities, and obviously the Bay Area is leading the pack. NIMBY voters and short sighted government officials are stagnating developers from building more units. Just a few weeks ago the city council in Portland rejected two housing projects that would've generated thousands of units and hundreds of affordable housing units.
When the public sector cannot solve the housing problem it is no surprise that the private sector will step in and play a bigger role. It's not surprising to see tech companies leading the way because their HQs are in the Bay Area. If potential employees don't wont to work for you because the area that the office is in has an astronomical COL that is an existential threat to your company.
