Where does this perception of hate come from for you?
On some topics feelings run high, and colourful or emotional language is used.
Look at the many, many threads on the Nikon Df on dpreview.com for one example. (For those living in a cave, the Df is a new retro-style full-frame camera.). People tend to strongly like or strongly dislike the Df, and anyone voicing a counter opinion is immediately villified, with escalating language.
We get the same thing about Adobe. Adobe are perfectly entitled to move to a rental-only model, and people are perfectly entitled not to like it. And some people really dislike it a lot, and say so strongly. As is their right.
Personally I don't like it much, but I've subscribed. I used to upgrade Photoshop every 2 or 3 upgrades (when you could do this) and upgrade Lightroom every time. The new $9.99 subscription works out about the same (in the UK) compared to upgrading Photoshop ever 2 upgrades (and Lightroom every time). But I'm not very happy, as Adobe systems are pretty bad. It took me 5 hours or more of phone calls and chat sessions to sort out my Adobe account before it worked, and judging by http://forums.adobe.com/community/creative_cloud?view=discussions
I'm very far from alone in this. People get charged twice, or not at all and have their use of Photoshop suspended. People change their credit cards (after Adobe kindly gave all our details to hackers) but then the system wouldn't allow them to change their cards. Some cards mysteriously get rejected. Downloading CC apps is a precarious and unreliable process. An update of Photoshop failed for me recently, and I had to uninstall and reinstall it. That's another 4 hours of my life I won't see again.
This is no exageration. Many people have no problems I'm sure, but quite a few do. Adobe have a lot of work to do improving their customer systems.
Then there is the rather changeable customer policy. First you could upgrade the last 3 versions of CS apps. Then only the last. Then CC rental only. Then the $9.99 package for existing customers. Then it was exteneded. Then it was extended again. Then for a while it was available to new customers. Oh, and Lightroom was outside CC. Then in. Then, eventually, a rather equivocal promise it will stay available outside CC.
People don't like uncertainty, and Adobe have been giving this in bucket-loads.
So with all this, it's really not surprising that Adobe should have attracted a degree of hate over the last year or so. They've got a bit of work to do to re-establish a stable, long-term environment for customers. And greatly improve their on-line systems.
