I researched it a bit more (meaning I googled it lol) and it turns out the plea deal had a clause which states CZ can never return back to the company. Not as the CEO, not as board member, not as anything at all, he can't be officially working there, he obviously has big part of the company as shareholder, and he is still 50+ billion dollar rich, but that doesn't mean he is going to end up with a great deal of power on that company anymore. Could he still phone them up and tell them what to do? Probably, I mean he is the founder, but they do not have to care what he says anymore.
