Oh wow there's a whole heap of interesting stuff there!
I guess Cinnabon thought:
A/ There's no such thing as bad publicity, and
B/ Gene's life overall is hollow, the job itself isn't the thing that's sucking his soul away, it's normal life in general (I mean Gene doesn't even seem to have any friends)
That and or they could have just been big fans of the show and also Breaking Bad and thought it would be neat to be forever associated with these shows. Jimmy might have done some questionable stuff over the years but people do love the character and they likely know that.
