Ask HN: Why do engineers hate salespeople?

What do you mean by "salespeople" here? Executives, C-suites, managers, or actual salespeople?

Speaking personally, I hate salespeople because they're always selling me something. Engineers, by-and-large, hate salespeople because the self-actualization of a salesperson is worthless. The best salespeople are typically the worst people. The best engineers (Woz, Ritchie, Lattner) can make a positive impact even in-spite of commercial interests.
