Random advice from the internet:

Should you quit? Probably not. Should you be exploring other options? Maybe...and that's mostly orthogonal to being employed at Uber but not entirely. Personally, I don't think it is likely that Uber is going to significantly change its culture based upon its responses (they look like hunkering down and lawyering up).

Now in terms of 'strictly concerned with the impact on my career' that looks like a moral/ethical the-ends-justify-the-means-approach. Here, there are two relevant factors. One is that there is very little certainty regarding how job hopping or staying at Uber will effect your career. The other is that there is a near certainty that people will judge your decision on moral/ethical grounds and that some will judge it as being reflection of a character that is ok with Uber's culture as described by recent events.

When hiring includes consideration of 'cultural fit' time spent at Uber will weigh into those considerations as a risk for companies with an orthogonal culture. Since the longer someone spends in a culture the more likely a person is to become acculturated, the duration of one's 'post-Fowler' employment might be considered when assessing the 'cultural fit' risk/benefit of previous experience at Uber.

I am not pretending that I know what will help or hurt your career: careers vary on an individual basis. I am pretending that what you do or don't do is a choice about who you are. The internet is not going to give you permission for either choice.

Good luck
