For folk who bought LR6 Standalone I think that adobe should carry on updating LR6 for good as people were good enough to give their cash to buy it, so dobe SHOULD repay that thanks by keeping it updated imo.
I really don't get why people think software is different from any other product they have purchased.
You buy something; you get a warranty for a period of time (usually 12 months) that will fix it if it breaks (think bug patches), but you don't get all the goodies they release in their next evolution of the product.
It's your decision as to whether you buy the upgraded version of not.
Exactly the same if you buy a car.
BUT... car manufacturers became wise to the fact that people like to upgrade their cars regularly - they like the bells and whistles, so along came PCP schemes - you pay a 'modest' lease on the car, and every three years, you in effect get to trade up to a later version.
There are benefits and disadvantages to both models, but you would not expect a car manufacturer to keep giving you a new car if you opted to purchase outright? It doesn't make business sense.
Just because software is perceived as intangible, doesn't make it ant different; people already get a better deal with updates being more freely available for perpetual licences, but there has to be a line drawn somewhere.
I'm on the line now as to whether a SaaS model for adobe will work for me going forward; I already have unlimited cloud storage through by Google Apps paid subscription, so I don't really want to pay for more on top of what I already have just because it's bundled with the package, and I'm not clear how LR mobile will be supported on the classic going forward, but as that situation clarifies, I'll make a decision.
Most if not all software will move to SaaS ultimately - it is already the case in business, with a massive shift in that direction, so I can see it becoming the predominate model in the consumer space too, but I think they need to work a little harder on making sure the 'offer' is attractive.
