Citing ongoing litigation, Adobe is warning its customers of legal problems if they keep using old versions of Creative Cloud apps [appleinsider.com]. It has not stated yet with whom or what it has the dispute, but early indicators suggest that it may be over copyright. Going forward Adobe is only supporting the two most recent versions of its Creative Cloud services.
"Adobe recently discontinued certain older versions of Creative Cloud applications. Customers using those versions have been notified that they are no longer licensed to use them and were provided guidance on how to upgrade to the latest authorized versions," said Adobe in a statement to AppleInsider.
"Unfortunately, customers who continue to use or deploy older, unauthorized versions of Creative Cloud may face potential claims of infringement by third parties. We cannot comment on claims of third-party infringement, as it concerns ongoing litigation."
Instead, users are receiving the equivalent of a cease and desist email, informing them that the apps that they are using are discontinued.
Gimp and Darktable are not perfect replacements but may be close enough for many hobbyists and maybe a handful of professionals.
