You don't get why people would be annoyed that a new requirement was introduced, that adds nothing, gains them nothing, and prevents a subset of people from playing?
The reason they can't play is because you can't get log in to the PSN in those countries, even though there is no real reason why Sony couldn't let you create an account.
And because they had played for 2 hours, you are no longer eligible for a refund.
You don't get why gamers are unhappy with changing requirements after purchase, to the point where there are literally petitions asking for government intervention to stop publishers from killing old games.
