From TFA:
> the city prohibits companies from fully subsidizing meals in the Village, and the rule could spread to other Bay Area cities in the future.
So no, it doesn't apply "only to Facebook", it applies to new office complexes, in this particular case the complex called "the Village". It would apply to any companies within that office complex, and potentially any new complexes and offices built in MTV going forward.
> For the SF rule, it is only proposed by Peskin and Safai. And Peskin himself said on twitter that this is just a proposal.
You only need one lawmaker to propose a new law. Plenty of laws in the book were proposed by one or two lawmakers initially.
> Peskin himself said on twitter that this is just a proposal.
Not sure what tweet you're referring to. The one I've seen seemed very serious and even militant:
> Announcing new leg to ensure on-site tech cafeterias don't continue to chip away at our vibrant neighborhood commercial corridors & small businesses. We're not the suburbs, we're an urban city with a vital local economy that corporations say they want their employees to support

He's saying it's even more necessary in SF than in MTV...
