A fair number of tech companies donate to SPUR, which does policy analysis/writing, advocacy, etc., including Dropbox, Salesforce, Netflix, and others.
That said, I was disappointed to see last year that Google apparently joined about the month I did (as opposed to, say, a decade ago) and were donating at some small level (sub-50k/year, Microsoft was in a higher donation bracket ffs). The amount of fighting Google is willing to do in Mountain View while ignoring the rest of the bay astounds me.

This article is about a big-ish tech company championing YIMBY.

I'm guessing Page, Ellison, Zuck, Andreesen, ...
But that leaves another Marc?
Larry, Sergey, Mark, Marc, Marc, and Larry all should be actively helping these efforts to make housing more affordable to their employees and those of the companies that they invest in. And they all can afford a similar contribution far more easily than you and Stripe can.
