"then rent increases are limited by law" In certain cases, yes, but personally I lived in SOMA in an apartment for 2 years and my rent was going to go from 2k to 3k because Google had asked the building if they could rent some of the units. So I mean, maybe it was illegal and I don't know about it, but I can certainly say I don't live in San Francisco anymore because I was priced out by new incoming tech employees.
