How is user generated content "expensively-gathered"? Content comes at exactly no cost to them so yeah it is lame. The data comes from community. Have you looked at the site?

Really? Setting up the site was free? Architecting the systems scalably was free? Popularizing it was free? Getting people to give their information to it was free? Protecting it from spammers and malicious activity was free? Securing it was free? Usefully organizing the data was free? Protection from lawsuits was free?

GlassDoor didn't just put itself together one morning, or a free, open-source one would already exist.

Do you also spread the meme about "Viagra was invented by accident", as if all the clinical testing, information dissemnation, regulatory approval, chemical isolation, etc were accidents too?
