But those are entirely different measures. Not worthy of a subscription does not mean not worthy of my money, it simply means it is not worthy of my money on a recurring basis. Perhaps I am one of those seemingly rare consumers that did not mind high one-off costs, even in my poorer years -- in the end you still own the thing, or at least it's bits. Subscriptions net nothing over the long term and their recurring spikes will eat people to death.
It's easier to cancel a subscription than get a refund on a license.
