I imagine the city would pick who gets to stay in the affordable units through a lottery or similar; IIRC, Facebook has a similar development next to their "1 Facebook Way" building. 10k housing units might be enough to give one or two years' worth of Google new hires an apartment; there's no way that it's sustainable to just throw it in as a benefit (plus the tens of thousands of existing employees would be outraged). I imagine they'd use it for temporary new-hire housing and/or intern housing.
