Why would they?
In fact, lots of people were already frustrated with the handling of "lifetime access" while having ads being pushed.
A business, Apollo, made an offer (lifetime access) to gain marketshare. It worked as Apollo is the defacto Reddit App for iOS. Now they cannot hold true to their offer, so they're forced to refund it. This is the price of the bargain Apollo made.
I feel terrible for Christian on an individual level. He must be going through hell. However, there is a business being run by Apollo and it needs to be held to it's commitments.
