Twitter gets extremely mixed reviews from people who are the targets of abuse, and I believe I am putting that conservatively. So, what I would ask is not whether they are going to lay me off because they run out of money, but whether I am going to quit because when I get inside, I discover that they are not going to actually do much about it.
If Twitter has had a come-to-jesus moment about abuse, and there are no structural obstacles to doing something about abuse, this could be a job where you will one day look back and say, “I was part of the team that turned the corner on Twitter’s biggest problem. I made a difference.”
On the other hand, if Twitter doesn’t have quashing abuse in its cultural DNA, or if there are deep structural obstacles to quashing abuse, then you may discover that you cannot actually make a difference. That can be soul-crushing if you are passionate about the work.
I am not making a claim one way or the other about where Twitter is with this, I’m just suggesting that if you are motivated by making a difference, the biggest thing to figure out is whether you will actually be able to make a difference.
IMO, this matters more than the financial risk.
