Hi!I recently quitted a startup that I spent many years at. I was the first employee as engineer, and I own equity (not option). The management team has changed drastically over the years, and the tech that enabled the business is now considered a cost. The politics got overwhelming, which is why I quitted. The startup has made a few private rounds and added many members to the board. The management does not like tech at all. They offered a price for my shares, which I said no because of the low offer. And I received a message from the management saying my shares are restricted and subject to board cancelation.I cannot tell if it is an unhappy/unreasonable threat message from the management or if it can actually be possible. In what scenario can a company legally remove your equity?
