In city politics, a handful of major tech moguls have always been active. Ron Conway and Mark Benioff have both historically been massive players in SF politics and have been supporting more moderate Mayoral candidates for some time, but the SF Board of Supervisors tends to filled only with NIMBY activists and real estate owners (Dean Preston, Aaron Peskin, Hillary Ronen).
Now that someone who is Seacliff adjacent is dead, they'll finally do something. I used to live in a Tenderloin adjacent neighborhood and my street literally reverted to mob justice after the riots because it was filled with working class undocumented immigrants+asylum seekers who were targeted and Tenderloin PD's hiring basically collapsed (on that note - if you're trying to stick up someone, don't stick up someone who fought in the Yemen Civil War and the Afghan Civil War. A couple people learnt their lesson in that neighborhood from what I heard at the local mosque).
While those riots went on, the police were guarding Seacliff, Russian Hill, and PacHeights. And it's those same people who's kids end up in SF progressive politics and setting up organizations that push these kinds of policies.
Btw, if anyone downvotes me thinking I'm some GOP nut - I'm not. My politics lean moderate Dem and I have worked in the moderate Dem space for years. That said, the SF Dems are entirely out of touch. It's a level of machine politics that makes Chicago look competent (and they've had actual Supes get arrested for arms trafficking, but then again so did we in 2012).
