Earlier quoted context omitted.
The mutual exclusivity is valid. Being able to do stuff that requires a lot of time and doesn't make a lot of money (i.e. art) requires a low cost of living. Adding a bunch of people making $200k+ into a neighbourhood does the opposite of that, very rapidly and very predictably.
Most people working for tech startups (as opposed to for Google itself) don't make anywhere near that salary, especially not outside the major US tech hubs. This campus would have been a startup incubator, not a regular Google office. That said, yes it would have still contributed to gentrification in a less extreme way than a true Google office.
But gentrification still happens without big dollar companies showing up. It's often a side effect of the success of the arts in the area. As the wealthy kids move in to be hip and cool, and the businesses that enjoy their money move in afterward, rents go up and creators are pushed out.
