Indeed. Click your profile in the top right, click on the settings icon. In Settings, select "Data Controls" (not "privacy") and then there's a setting called "Improve the model for everyone" (not "privacy" or "data sharing") and turn it off.

so they technically kind of follow the law but make it as hard as possible?

Personally I feel it's okay but kinda weird. I mean why not call it privacy. Gray pattern, IMHO. For example venice.ai simply doesn't have a privacy setting because they don't use the data from chats. (They do have basic telemetry, and the setting is called "Disable Telemetry Collection").
