Alternatively if the difficulty of moving from 0->X is not negligible but moving from X->X+Y is then I may still be installing but I'm not considering the Y in the comparison then either. i.e. If I have to show my id to google once and apple twice it's the initial showing that is the turn off, or if it's the action of getting my credit card out in the 1st place rather than the cost difference that concerns me.
The key difference being that when I needed help I called Apple Support who transfered me once to their EU Developer support who, while I talked to him, setup and approved my Dev account. While my Google account still is in pending limbo with their new verification system with no support to contact... I have since giving up getting access after multiple tries.
So Google changes do hit alot harder than the summery makes it seem.
