I just don't understand this naive argument against subscription. If I have to pay same amount of money, I will pay in subscription than paying one time. So let's say average subscription time is 2 years, they can make $400 onetime or $20/month to get the same revenue. As a consumer I will prefer the second option.

For $40 product, I will rather pay $1/month than $40 once. It keeps the incentive aligned. I think most people just assume that if the devs move away from subscription they would be fine with lower revenue and would charge less.
