> The founder accused Horvath for bringing love affair into the company because she was/is dating an employee. The founder has a good point: try to avoid dating someone working with you. It's a beautiful story; but you can cause all sorts of mess.

That's between the two people. Period. If they become problem employees, then they are problem employees, not two people who date. The problem behavior that happens on the clock is HR's only legitimate concern.

Prohibiting dating is like firing women who get pregnant.

Counter example, where I work there are so many married or dating couples within the company that it's almost a thing.
