...Adobe isn't exactly resting on its laurels and allowing their products to stagnate. The thing is, if Adobe had been consistently developing valuable new functionality and making it available in newer versions, their customers would have been paying them to upgrade in the previous model as well. The fact that so many people didn't see enough added value to buy each major upgrade suggests objectively that the produc…
Also note, Adobe's products are known to be some of the most pirated pieces of software around. During my high school and college times, everyone I knew owned pirated copies of Photoshop or Creative Suite. Same folks now just pay the monthly fee to have the fully updated and activated product because they can't be assed to fight activation issues periodically.
If that is anything close to accurate -- and I stress the "if", because the data is probably at least third-hand here -- then Adobe would have lost more than half of their previous customer base in the transition, and still not regained them several years later. If a significant proportion of those they have gained are ex-pirates, that's an even stronger suggestion that their own permanently licensed products prior to CC might still be their biggest competition.
The situation with pirates seems less relevant for most of Autodesk's products, as their market is much more likely to be professionals than hobbyists anyway. But the implications of earlier permanent offerings potentially representing ongoing competition for their new subscription-only model even several years later would be just as unpleasant as they are for Adobe. Anecdotally, one of my companies has some big name Autodesk software for use with a specific part of what we do, and we've just decided that we'll make do with the existing systems and not buy any more or any updates if they're only going to rent new versions to us and won't let us buy any more copies of the existing version we already use. If significant numbers of larger businesses that already have spare capacity in their volume licensing deals decide to take a similar approach, that definitely won't be good news for Autodesk's new strategy, but I guess time will tell.
