I think part of the issue with moving from physical media as a form of software distribution is that people ship buggy software all the time. In addition to making more money via subscription, the company can ship updates whenever it wants. This often means that 1.x may have bugs still present in 1.z, but 1.z has features not originally included in 1.x. At a certain point you’re maintaining several versions of your product to test bug fixes, since 1.x users still deserve the bugs fixes but technically shouldn’t have the 1.z features. Better companies would be able to handle that, but nowadays bug fixes get extremely low priority since they’re spending a lot of dev time trying to attract and retain users with shiny new features, so that means active development on older versions for longer. Obviously the subscription revenue is also generally appealing.
