GameRager: The first part: One can/should make multiple backups to further mitigate such chances of loss/failure.
Second part: If the store in question didn't have the rights to offer such then it's not their fault for doing so/they have to do it legally(luckily this doesn't always happen) to avoid lawsuits from devs/etc.
Indeed people should always have multiple backups, but how many actually do? Very few. Most people don't even have one backup. And if the original source is removed, then the a backup is
no longer a backup, but rather it becomes the primary source.
And anyway, even if people
did have multiple backups, that
still wouldn't be an excuse/justification to steal paid-for games out of people's account's anyway. I'm sure the consumers who paid for those games have legal rights that make such theft illegal. And if they don't, then consumers need to court-challenge such acts of theft until judges
do give them those rights.
The bottom line is that no matter what possible excuse is given, the idea that games that people have bought can be arbitrarily stolen from their accounts is, as I said, totally outrageous and if they actually have the gall to do this, then this crime must be fought tooth & nail.
