If someone does something wrong, Alice tells them plainly, and they get offended, whose fault is it? Some people say it's Alice' fault for offending; some say it's the person's fault for doing it wrong in the first place, and for subsequently getting offended.

I think we're conflating is and ought here. It's probably a fact of reality that most people aren't happy to be told they're wrong. But arguably people ought to accept the consequences of being wrong, e.g. feeling bad when they're told.

I've talked to lots of startups in San Francisco. Most are failing, just due to the nature of startups, but can survive if they reach a finite set of straightforward goals. They've found product/market fit, they know what they have to do, they just have to do it, and the correct 10,000 characters of code input into a computer would solve all their business problems. There's often a lot of handwringing about why they're failing: the process is wrong; communication is wrong; something or other. But the largest reason they're failing is that they're insufficiently good at technology. You know who'd be really good at fixing that? A team of Alices.

I think Alices get too much flak. Bob is genuinely a toxic character. But if your only fault is telling the truth, which offends people, and you're otherwise excellent at your job--- there's a huge opportunity for twenty Alices to get together, bypass the inefficiencies of being offended, and win big. Tech has an obvious historical example.

Edit: I reread the description of Alice. All right, maybe don't browbeat your point into others.
