Notice that in some places (with good enough customer protection rules) pre-paid credits can't expire, as expiration itself is a clear abuse of market power: they are forcing out revenue from services not given, even if it is "made clear at buy-time". Especially at such short time horizons like 1-year.
And yet they are supposed to be the good guys.
Of course it is just an excuse to "fuck the customer" and grab the money, but it is not something you should question, because in our society you don't question how companies make money.
And it doesn't matter if you are the offended part, people will just protect the state of affairs,even at their own expense.
Just look how people always find a justification for this crap and look how you are being downvoted for pointing another one.
It's not like the game had fixed rules and everybody is playing by the same rules.
The rules are made by the players, while they are playing the game.
The problem is that are players following rules the benefit all players and are other players doing rules that benefit only their own at expense of the others
