As someone who’s been involved with involuntary resignations - what normally happens is they get called into a meeting, and they get told “we think it’s a good idea if you made way, and give someone else a chance at the role. The recent <information> has made it more difficult to perform your role so we’d like to get some fresh blood in. If you could resign in the next few days, we’d appreciate it. We’ll give you a nice bonus for leaving.”

It’s absolutely never worded in a way that’s adversarial, because that’s asking for a law suit. Its heavily incentivised for them to leave “of their own accord”

It’s got nothing to do with dignity, but about avoiding lawsuits for someone being fired without a good reason.
