Founder here of a 300 person startup. It's appalling and infuriating to read stories like these.
I started my biz because I wanted to make products that people love, that create value and timesave for others (specifically restaurants). I've always thought that if I do that and have a good time doing it the money will take care of itself.
I would be horrified if some PE firm rug-pulled our users and screwed our employees. Any such takeover would have to happen over my dead body.
