It seems as though nobody in this thread actually read the article. They are not revealing user names on the site. The objection here is having the real name as part of your private profile data, in case of a future data breach. It’s a real concern, but orders of magnitude less serious than what everybody is assuming.
Shame on Ars for the misleading clickbait headline.
Agree that it's misleading, but to add there is another significant concern given how glassdoor is already "pay to win" from the companies perspective: they could just offer identifying the users as a paid service.
It would be digging their own grave if that starts happening, but that doesn't seem to be stopping many companies..
I'm more concerned that the company decided it was OK to meld the "From:" line of her email (asking for support) into her profile. If they think that's an appropriate way to handle PII, I don't trust them.
For a supposedly anonymous site that's going to be a target from both hackers and companies looking to reveal that data, I'd say it's not really any better, just delayed. All it takes is someone finding a SQL injection vulnerability on the site to scrape the user database, or a court to rule that they have to turn that data over to a company looking to go after an employee, or even just someone with the right access at the company clicking the wrong link
If you want to be anonymous, the first step is to not give people your name or other PII
