You're misunderstanding the difference between a voluntary exit and a firing. This is not standard procedure for a voluntary exit at most companies. The employee puts in their two weeks, works the time, and exits. The assumption is good faith on both ends, because the employee has chosen to leave. It absolutely is the standard procedure for GETTING FIRED. The other standard part of getting fired is that the company has already decided they no longer need your skills or expertise (excluding twitter's situation, where they decided poorly - according to the news). If you're laying off 100 people - the odds that any one of them might do something silly is very low. But that chance * 100 is usually considered an unacceptable risk from a security standpoint. Multiply it by several thousand, and it's absolutely not ok to leave the keys to the kingdom with that many fired employees. All it takes is one drunk employee holding a grudge and you get a really nasty mess on your hands. Not to mention legal hot water.
