I'm not oppossed to frat bro culture tout court. As long as employees aren't being harmed and productivity is high, then the choice to work at a place with just such a culture is like the decision to choose to work anywhere. Pretty standard stuff.

However, people can mistake a frat bro culture with actually high productivity (leaving aside questions of whether employees are harmed by the culture). Zenefits pre-Parkers-leave might be an example. Employees can't be getting drunk and having sex in stairwells during office hours and retain a high level of productivity.

The real problem is that Uber's lawbreaking and unethical behavior stems directly from the "bro culture".

That's a rather strong claim. What's the causal relationship here? All frat bro cultures necessarily create lawbreaking and unethical behavior?

From my perspective, that would be prima facie wrong. I've witnessed frat bro cultures that led to that and ones that haven't. Just like every other type of culture.

Maybe we aren't talking about the same thing.

The tech "bro culture" values being extremely aggressive, competitive, and ignoring norms of behavior. That sort of mindset leads directly to lawbreaking and unethical behavior.

Yeah, I think we might be talking about different things.

What I have in mind is a culture where personal boundaries are a bit relaxed, people are abnormally loud when communicating, etc. There is a sort of shallow resemblance to general sports culture.
