Gentrification is a real problem, with inequality at it's roots. I think most people would agree with that. And I'd also agree that it's easy for some in the tech community to lose touch with the relative privilege that they often live in. But this is not a "reasonable backlash" – it's a bunch of incoherent knee-jerk harassment by people who should really be doing something better with their time.
The proper channel for dealing with housing issues is local government; for NSA issues, national government; in neither is the correct channel the harassment of individual employees of a company which may (or may not be) the cause of those issues.
