What a load of corporatist bullshit.
>alias users are misfits or troublemakers
No. Fucking NO.
You have the right to call yourself whatever you want in real life so long as you are not trying to defraud anyone while doing this. That this right supposedly suddenly doesn't exist because a corporation demands it is insane.
This does not make you a misfit. It does not make you a troublemaker.
Aliases have a history going back decades online and thousands of years offline. This sudden "hurr, you must use your real name" in a contract-of-adhesion is such bullshit.
You may believe that corporations have special rights to deny you your rights, but I don't, and neither do a lot of other sane individuals.
If Facebook's share price loses a few pennies because people like me use aliases, it's not my problem. They can find another business model.
