It’s not a “penalty” to be allowed to sign up simultaneously with everyone else. It’s not like they owed you “a spot in line.” They never promised you would be allowed to sign up early, and you didn’t pay them for such a right.
It’s just a credit card. I want to sign up too, but I can wait.
Of course it's just a credit card. However, there was an ostensible process in place that invites were issued in some order relative to when people expressed interest and because of a glitch, this group of us, according to your probably accurate assumption, means we are losing our spot in line. I am not shedding any tears but it is penalizing to lose one's spot in line because of a glitch.
