...So far I see subscription as more affordable way to get an expensive software even if it means paying more in the long term.
Except that with the "Creative Cloud" system it is not a more affordable way to get expensive software. The "affordable" model Adobe instituted and followed for at least two decades was the "upgrade" path. Make your initial investment in the software and then, over time, you can receive discounted upgrades and expansions, until ultimately, you have a full suite of software available to you at a substantial savings.
The trade off was clear – you got rewarded for being a loyal customer and Adobe had a built-in base of customers for software upgrades. One of the frustrations with the new Cloud system is that Adobe is changing the rules on users who have played by their rules.
I've done the math every which way and even with the special introductory pricing, customers end up paying more. But, as others have said, the money is only a part of the problem. Many long-time users felt some loyalty to Adobe and were their best advocates. There are many other issues as well.
