Good & bad in judgment on Meta AI training & personal data (legitimate interests, sensitive data) + new French & German guidance

Does training of AI systems involve the processing of personal data, and is it permitted under the GDPR?

ePrivacy challenges – one cookie law to rule them all? [Part II]

Time to talk about what can be done to improve the “cookie” rule! In Part I of this series on the opportunities and difficulties of today’s ePrivacy regime, I discussed the underappreciated and seemingly-easy-but-really-complex world of the anti-spam rule, Article 13 of the ePrivacy Directive (or ePD).

Without the ePrivacy Regulation, which challenges must still be addressed? [Part I]

Now that the Commission has withdrawn its proposal for an ePrivacy Regulation, where does that leave the ePrivacy Directive and the issues organisations face?
