Buy an application or subscription, what do you think?

I don't mind paying for a subscription, the problem is that almost all the current business model is subscription based now.

I prefer to pay xxx for an application instead of paying a subscription I think Apple should take the time to look closer at all these apps with subscription.
Often the subscription is in no way justified, and for personal use of some applications for example for the 3D sharp3D. 239 standar a year or 499 professional for some personal use is incandescent I find.
Or even applications that I paid for that are now free with a subscription.

I wonder what you think of this evolution?
