Their publisher decided it. And it’s probably in the contract. Apparently it was originally a requirement, but was made skippable when there were login issues.
The only thing they proved by making ot skippable is that it wasnt even necessary at all. The reason they’re giving for making it mandatory ( for security and being able to ban for griefing ) is bullshit. Not to mention They’re already using a super invasive anti cheat, which apparently isn’t capable of catching any cheaters.
