Fed up ricecels most likely. We Asians are way over represented in tech here in SF/Silicon valley. The stop Asian hate movement led by anonymous trolls on social media seems to be working. Although that and covid actually made the WMAF phenomenon far worst, the movement has made a lot of Asian men more politically active. And even before that, there was Andrew Yang of course. Its not just Asians either. People are fed up in general with the bay area.
The only people who like the bay area are racist yet liberal upper middle class to upper class white people, foids, chads, noodlewhores, and liberal beta white males. Dead serious. Everyone else pretty much hates it because they are excluded. The bay area is nothing at all like what it was before. Its almost completely over-ran by transplants from the midwest and east coast.
