No thanks. If they ever bring out a compulsory subscription model with no option to buy, that's where my interest would end.
I really can't believe the majority of people want a subscription model for any apps, be it Office, Adobe, Roland Cloud, or whatever. I'm pretty sure the majority of us would just rather buy the products outright. Renting apps forever which you never truly own is a model straight from the bowels of hell itself, because basically you can never stop paying.
