I totally get that, but it is what you paid for it. As long as it is greater than your original payment adjusted for inflation it's fair enough. It sucks, I think there should be some sort of penalty for not getting proper licensing to let people use it forever (until your company shuts down).
No, it's what you paid for one specific digital item that was valuable enough to you to be worth paying for. That doesn't mean that anything else they have to offer would have enough value to cover the value of the item you've been deprived of.
Usually if you complain you can get a real refund. The other post was Amazon and they usually bend over backwards to make customers happy. Still pretty shitty that you have to jump through some hoops, though.
