"blame-the-game-not-the-player" is so typical of polite SF (and greater CA). A lot of homeowners are quietly rubbing their hands knowing their houses suddenly got more valuable.
My experience with SF rent control is that it's really only valuable if you've got limited resources. I lived there for 5 years, saw market rent double, and my landlady politely asked me to pay a "generous discount from market", which was about a 50% increase and I declined - it would have busted my budget.
Then eviction proceedings started: completely made up, and I lawyered up. I was threatened with OMI (there's no defense if they actually do move in), and I negotiated a settlement. Because if I'd won I'd have a super hostile situation ending in OMI, and if I'd lost I'd have killed a substantial portion of my savings.
If I'd had nothing to lose, I'd have hung on for dear life.
