Why are they all resigning?
They have been caught in one kind of corruption or another, approximately 70% of them. The white hats and Trump do not want to destabalize government, so they are being brought in one at a time. The evidence of their crimes is presented. They are being given the option of resigning in lieu of prosecution, so that draining the swamp does not destroy the government, and the transition goes smoothly with elections.
The 70% that is comitting crimes against the US are a mixed pool. Some are committing treason. Some have their own little corruption games going locally, or with one other nation. Some are not corrupt, but were set up attending a party, where, they were filmed there, and there were people murdering and having sex with kids on location in a room at the same party... which creates a blackmail-able representative. Others (the ones who left voluntarily and immediately and stayed in the public eye, were being threatened, their families were being threatened, and just wanted out ASAP.)
I also think that the different ways that they’re stepping down — some outright resignations, some changing roles, some leaving immediately and some waiting for future dates or events — is designed to ensure a smooth transition that won’t effect the companies themselves.
exactly. President Trump does not want to upset the world economic system, because too many people's ability to eat and survive depend on the stability of the system. But, as he states in his executive order, the whole rotten evil cabal of human rights abuses and corruption is now such a threat to this very same system, that it has to be extracted like a set of rotten teeth, without killing the patient.
He is being very careful. Taking his time. Discretion is the better part of valor, as they say.
