Do a forum search on "creative cloud" and you'll find many exhaustive discussions of this topic, for example -- Adobe - Creative Cloud Update.
Extensive -- yes, exhaustive -- hardly.
I just browsed/searched through all 27 pages of the topic that you suggested, but there's no post that covered my case.
I had two copies of LR5; bought one for myself, another for my daughter. Then LR6 came out, and I tried to upgrade... And guess what, upgrade was
not available in Russia. It also wasn't available about a month or so ago, the last time I checked (out of curiosity). Here, "not available" means that, when I go to
LR page and select that tiny "desktop version", I was taken to the "Dealer selector" (or something similarly named, can't remember), and an attempt to use it would cause infinite page re-loading loop. In any browser except Firefox (again, IIRC), but there it would just lead to some other Adobe product selection page, so yeah, another infinite loop of sorts.
Calling their support in Russia would get me to Softkey.ru (or whoever was their "official distributor" at the time), who would happily inform me that there was no such thing as an upgrade for LR5. I could only get a discount if I was a student, or a rep of a government institution or something... And I could not even get to adobe.com to call their support (as a last resort), as going there always redirects to
http://www.adobe.com/ru/, immediately. BTW, softkey.ru (
) only sold Adobe products for rubles at an insane exchange rate that was about 20% higher than current at the time. To add insult to injury, they (read == Adobe) would only deliver
electronic copy of LR6 in about 10 days! WOW!!! Electrons must be real slow at Adobe.
So what were my options? Stay at LR5, or buy two
new copies of LR6? I chose option #3: no more commercial Adobe products for me, ever. I just went on and bought ACDSee 8 Ultimate, and since then already upgraded to ACDSee 9 Ultimate. To compare LR to ACDSee would take another post, but let me say I'm very, very happy... Of huge importance is the fact that, unlike LR (or pretty much any other program supporting "non-destructive editing"), ACDSee does not lock you into their catalog, in any way. And you do not have to "export" anything -- all edited images are instantly accessible by any other program.
Now... Creative Cloud was being pushed by Adobe into my throat with such energy that I now consider them the kind of company that would run "7 viruses discovered on you phone, click to clear!!!" blinking ads. And that's not an exaggeration; if I wanted to exaggerate, I'd say they the the kind of people who'd loot abandoned homes during a war, search corpses for loot, and/or take a candy from a kid. Bottom line, I can no longer trust them, at all.
