Hi father,

I'm not sure how they can force you or anyone to pay repeatedly for anything without changing the EULA. I suspect if they were to change the EULA to allow what you're suggesting, you wouldn't be the only one to find somewhere else to purchase their content. In fact Daz have already announced that a free decrypter utility would be held with an Escrow company to be released at the time of their demise "or is unwilling to continue offering this as a free service" and are in the process of updating the EULA to reflect that.

But of course you are free to spend your money wherever it brings you the most joy. :)
