@baldur According to the Creative commons video, if you create something you have automatic all rights reserved copyright of that work. If adobe are using with out your permission then this is clearly a breach of copyright and therefore illegal.
The fact Adobe think they can trick people,so that persons work can sinply be used shows how arrogant big tech is.
Any Opt IN or Opt OUT should be crystal clear in wording and implementation.
Treat them as they would if you shared their software online illegally, prosecution or lawsuit. The laws that protect IP work BOTH ways.
