@lfa it sounds like people can express they DON'T want their works to be used in Al training via #AIPreferences , and that #CCSignal is for people that do want their work to be used in specific ways.
A great many people already post their work to the public domain, or creative commons: #AllRightsReversed , #CopyLeft or via similar licenses.
If #AiPreferences already supports the #NoAI preference then it makes sense to me to offer content creators #CcSignals for more fine tune control.
