If you have an Adobe account, for Acrobat or Photoshop or whatever: they've turned on the "we will pillage your work for AI" setting.
Go to https://account.adobe.com/ -> Account and Security -> Data and Privacy Settings -> Content Analysis. Turn it off.
If they want to learn from your work, make them pay for it.
[Edit to add: before you gripe at me about using Adobe, read https://mwl.io/faq#tools ]
