That's extremely rare, in my experience. Nowhere near what developers go through. It's rare even for basic things like spelling errors or typos to be pointed out, let alone more serious problems like a presentation containing statements that are wrong or vague, meaningless, etc. If people get their work criticised so easily why are there so many spreadsheet errors around, why are there so many vacuous PowerPoints and business processes that go round in circles leaving behind furious customers? I've witnessed all this first hand. I've also seen what happens when programmers and non-programmers in a tech firm get accidentally mixed together: the programmers start pointing out mistakes in the non-programmers work and cause an "incident" because the others aren't used to being peer reviewed like that.
