It only takes one person to fuck it up. I agree it’s stupid, but introducing a conflicting standard increases the chances of someone fucking it up in the name of progressiveness. Needless to say I killed off the main branch that someone one had tried to make to replace the master branch.
I’d never signed a credit or debit card in my life until I travelled to the US last year, and then I only did it because I’d heard stories of places confiscating cards if they weren’t signed. Don’t know how true they are now but I wasn’t risking it.
