Docusign just admitted that they use customer data (i.e., all those contracts, affidavits, and other confidential documents we send them) to train AI:

They state that customers "contractually consent" to such use, but good luck finding it in their Terms of Service. There also doesn't appear to be a way to withdraw consent, but I may have missed that.
