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.
NIMBY = Not In My Backyard, don't build new housing that will drive down the price of my house/rental unit.
YIMBY = Yes In My Backyard, please build new housing because I don't want to spend 75% of my salary on housing but I still want to live in the city where my job is.
