How could this possibly comply with European "right to be forgotten" legislation? In fact, how could any of these AI models comply with that? If a user requests to be forgotten, is the entire model retrained (I don't think so).
and finally the most aggregious and dangerous: censorship at the lowest level of information before it can ever get anywhere near peoples fingertips or eyeballs.
I don't believe that is the current interpretation of GDPR, etc. - if the model is trained, it doesn't have to be deleted due to a RTBF request afaik. there is significant legal uncertainty here
Recent GDPR court decisions mean that this is probably still non-compliant due to the fact that it is opt-out rather than opt-in. Likely they are just filtering out all data produced in the EEA.
Likely they are just hoping to not get caught and/or consider it cost of doing business. GDPR has truly shown us (as if we didn't already know) that compliance must be enforced.
