Thanks to some sleuthing by pony fans this interesting tidbit of information has popped up! Before the lawsuit news broke, on the FontBros page for Generation B they had a line reading 'Generation B is one of the official fonts used in the TV series My Little Pony: Friendship is Magic! Enjoy, my little Bronies!'
So apparently they have known that the font has been used for quite a long time so maybe it was only recently that they found out that the proper licenses weren't purchased. All we do know is that the line is no longer on their site and can only be found now using the Wayback Machine and other internet archive sources.
So what do you guys think?

(UPDATE: It's looking like this is a secondary URL that shows the missing My Little Pony point. A different live one has the message on it)
