It amazes me how a company can make a decision like this without anyone in the team stepping up and saying "Deanonymizing users will make people mad".

It really indicates bad management - That either the decision-makers have enough unearned confidence to make this change despite the negative feedback they're receiving, or that nobody who actually understands the user base feels empowered enough to speak up and say that this is an unethical way of doing business.

I perfectly understand the decision to stop allowing anonymous content, but it is absolutely insane to apply this decision retroactively to content created by users who operated with the expectation of anonymity.
