Legally they can't use your data without your consent and that data must be able to be deleted by your demand. So for GenAI to use personal information is bad and they should change its design. I advise they obfuscate the data to not contain sensitive information if they are intending to create AI around such data. Identifiable information is not a good thing. GDPR and many other laws are still applicable to what GenAI is.
