Can we please stop using "gaslighting" as shorthand for "an opinion or perspective expressed by a single user that I disagree with?" I've seen it in several comment threads here in the past few weeks and it's getting really annoying.
I think you could also identify similar negative consequences from any entity the size of Facebook. I think it’s a side effect of being big, and fb is no different than any of the F1000 or just about any government on the planet.
What I do see internally — executives down through rank and file acknowledge the problems and work really hard to address them. I haven’t seen the same level in introspection elsewhere, even when I worked for the DoD.
