This hate comes from those who want to crack it (myself included). If you are a person that just want to use photoshop to mess a little bit and nothing else (like me), having to pay for it really sucks. But if you are a large enterprise, then is just the same paying for subscription or one-time fee
Hate is a strong word. I am venting extreme frustration at subscription only software. To be clear, I am not actually wishing someone be sent to a hell, it is just a common expression of extreme displeasure.
I actually do own, and paid for, a full legal copy of Adobe CS6 and enjoy it very much. Before that I had CS1, also a full paid legal copy. Upgrading from CS1 to CS6 was great. Even though it is not as expensive, I had a similar upgrade path by using Filemaker 9 for many years, and now just bought Filemaker 13; which is awesome.
So I am perfectly willing to buy expensive software when I can financially, and when my needs justify it. However, I detest having to rent software and then the very moment I can no longer pay I am shut out. To me that is bad business.
I do understand that subscription software is attractive to businesses and enterprises, since they can list it as a monthly expense; or if they pay for a year in advance they can amortize that expense month by month for that year. So by all means offer the option of subscription software to those who want it, but it is another thing entirely to offer
only subscription software.
Autodesk is a good example of a balanced approach; they offer both subscription software and a standalone copy of nearly all their software. I would very much like to see both Microsoft and Adobe take this approach.
