Every decision a company makes is about maximizing profit. that necessarily means saving on labor costs, which means firing people, paying as little as possible, extracting unpaid overtime (e.g. "crunch"), etc. That being the case, most every decision made by a company is about screwing its workers. You can argue about whether that's "evil", but it's an economic fact.
