Slimy is telling a woman she can't be called a cofounder because "she's a girl". Slimy is threatening to fire a subordinate if they won't date you. Slimy is ignoring complaints from an employee about sexual harassment. Slimy is firing someone for trying to exercise their rights to not be harassed.

Using clear language to communicate boundaries isn't slimy at all. It's reprehensible that she (allegedly for the pedants in the crowd) even had to say those things. Building a case when no one does anything about a pattern of continued discrimination and harassment it's slimy at all; it's exercising your basic human and legal rights.

What was the alternative? Not documenting the abuse so that it could get dismissed as a he said/she said argument? Deciding between putting up with the abuse or throwing away all the hard work she put into the company?

Apparently her options were to be slimy by documenting her case, or to get dismissed as a bitter woman who was blowing things out of proportion because she got dumped. Nice.
