Because just as individual contributors change employers a lot, managers also change employers often enough that the reputation of mistreating workers doesn't stick to anything.

My own employer recently hired a handful of senior HR folks from Uber. They started after I joined. I hate it, but what can I do? I know they were present at Uber during Susan Fowler's very strange year; I don't know if they were actually the people making decisions. And if I preemptively quit, what is my guarantee that the next place will be any better?

Trendy companies tend to hire young people who are desperate for a career-starting job. As an individual they have no power in that situation, which I suspect is why this letter has been signed collectively by a lot of Buzzfeed staff.

Because it's a company with at-will employment. Businesses are operational functions that maximize value for a pool of shareholders. Unless you're in the pool, you're a cost and a liability.

They prey on the young. Look at BuzzFeed's staff demographic. A lot of them are younger than 35. Five years ago, BuzzFeed, at least in the journalism community, seemed like the place to be: the company was growing, their news team was just getting off the ground and the resources seemed endless. One would think the traffic brought in by Disney princess quizzes would pay the bills. Sadly, that is not the case.

Video is still king over there. I'd be curious to know how many videographers and video editors lost their jobs compared to reporters.

Could be because they're companies. And it's not like BuzzFeed has a reputation to lose.

Because Buzzfeed is not a trendy company. It’s a tabloid dressed up as journalism.
