It seems like a joke to me (even if it is meant as serious) because he couldn't sue for the said creations since they belong to EA. I'm not sure if he can still mess with their hosting provider? (Wouldn't put it past the scumbag to try if this is real) I don't know, but I think they should be fine.
ETA: True he hasn't mentioned anything about suing, I only mentioned it because he has no legal rights to them
But yea true the hosting company might get nervous and not care to find out the true facts before acting. Hmmmm
