You know I was thinking about this last night, and I actually think the issue is far bigger than corporate Vs amateur user, or perpetual Vs rented licensing etc. I think this will affect the WHOLE photography and camera market around the world, from camera sales, computer sales and laptops, external storage etc, right through to book sales and website advertising revenues.
Lets imagine some time in the not to far distant future, I already own a camera such as the 5d Mk III, I am running CS6 (which is now no longer supported by Adobe) and I don't want/can't afford to sign up to the cloud, as I am a small business or amateur photographer and need to keep costs to a minimum.
Canon then releases the 5D Mk IV, which has a couple more mega pixels of photo sites on the sensor and a few more bells and whistles added, as they did last time from Mk II to the Mk III. But what may have been an obvious upgrade route to me, has now become a dilemma, because as I already own a camera in the Mk III that works with CS6 just how I want it to and with my preferred workflow and I am happy with the situation, or I can forego all that and choose to buy the new Canon and try to find a fudged way around to accessing every single image that I create on it, as that upgrade will necessitate a complete change to my preferred workflow or the cost of buying into the cloud and all that entails - so the choice boils down to this - do I upgrade to the new camera, or do I stick with what I have already got, for both camera, software, computer system and manuals, guides and plug-ins etc?
I would most likely stick with what I have got and Canon loses a sale, as well as all the small businesses and training companies and book sellers and software developers etc., as do the computer manufacturers and O/S developers, that I would have also spent money with and who rely on me upgrading my camera and computer system and plug-ins every few years or so, they have all now lost sales.
Fair enough, I know that at some point in the future when something that cannot be replaced has broken, that I would be forced into some kind of an upgrade, but assuming the above scenario is correct, this would be postponed until I absolutely had to and not before.
I think this scenario is not going to be far from reality for many thousands of photographers around the world and as such, Adobe are going to put quite a few people out of business with this move, so even though it may be good for them, in the long run, a significant section of the smaller associated businesses will surely suffer.
