Idk the specific comic but if it's banned in Sweden it's more likely that Tapas only has limited broadcast rights, like they might only have the right to show the comic in the US because someone else has exclusive access to broader exploitation rights or the creator/publisher simply wasn't comfortable granting international rights for whatever reason. Usually when you're an artist working for a publishing house, you don't want "free widespread international publishing rights" to be given over to the publisher,right away as a rookie because if your comic gets popular enough to go international, you'll want to renegociate your contract up to make sure you have a fair share of the revenue from your work, which'll probably be better now that you've proven your worth to them.
Rights are also usually given over a finite period in contracts that are fairer to the artists involved (to make sure renegociation is possible if unforseen success happens, or that contracts can end cleanly if it's a flop) which would explain why some comics are available in certain countries over a 1 year - 5 year period and then bounce once the contract is up.
