These are linked. Most of Downtown SF's desirability was you can work there and make a lot of money. When you could suddenly work other places for the same money, the main reason to go was gone. SF's pandemic policies exacerbated this by further driving certain people away from the city. Without office workers to put pressure on the city to keep the area safe-ish (or at least hide what's going on), the TL spread. And now, even if people return to the office, there's no reason for it to be in SF.
