This is very bad advice.
OP definitely should not do anything that might give the impression that they are abandoning their duties or, worse yet, actively sabotaging the company. That would be a dream come true for the other person’s lawyers.
If the OP wants to keep his equity, he needs to continue fulfilling his duties and demonstrate that he is, in fact, still working for the company.
Please don’t follow petty HN comment section advice like this. Not only is it unprofessional, but it can quickly turn into self-sabotage. Play it clean and don’t give the other side ammo to use against you in court.
