A related question I have is, what happened to everyone who held stock at the moment it was taken private? For large shareholders, ok, you can make a deal with them. But if I'm an employee or even just a random guy who keeps, say, $30k or $300k worth of Twitter stock, what happened to those people and their stock? Was it forcefully exchanged for cash in their Robinhood or Fidelity accounts? How does that even work?
