Yep subscription seems to be the preferred business model,
Steady revenues "if" successful
I'm not a fan no matter what the product with my limited cc6 tour which might qualify as a possible successful attempt I'm still not a fan of the unpredictable updates to the product which could render it dysfunctional very easily,
Just the constant uninstall and re-install is a pain in the neck than there's the work flow loss which is the worst part if business reliant :/
Bad times ahead if Microsoft does this to an operating system
