There is a YIMBY group in my city and I swear half the Twitter followers have "dev op" or "scrum pro" in their profile.
They also seem to have no interest in any other broader social or economic issue. Zip about poverty, climate change, reproductive rights, trans rights, etc. It's about market housing. Pure and simple.
As a person who left the Bay, is in tech, was tangentially involved with YIMBY groups, and is a socialist, it's because the most unaffordable places in the country are the places where you can get a high salary in tech.
And also because fuck rich white NIMBYs.
