The team began sending some users of Lightroom Classic, Photoshop, Premiere, Animate, and Media Director apps a letter with a warning that users are no longer legally authorized to use the software they may have thought they owned.

“We have recently discontinued certain older versions of Creative Cloud applications and as a result, under the terms of our agreement, you are no longer licensed to use them,” Adobe states in the email. “Please be aware that should you continue to use the discontinued version(s), you may be at risk of potential claims of infringement by third parties.”

The team doesn’t inform users about the reasons for discontinuing use of the software. Dylan Gilbert, a copyright expert with consumer group Public Knowledge, commented on the situation.
