It's not a 'leak'. It's in the T&Cs you agreed to. This is the business plan.
if you have an individual who has been sexually harassing others regularly the problem exists both with the individual and with there not being clear reporting standards, remediation processes, and person-by-person training opportunities (or only offering lackluster, barely enforced versions of the training)
organizations, especially ones as large and well-funded as LLM model providers that can hire whole fleets of trainers, ethics watchdogs, etc, that then produce large-scale, systematic incompetence are and should be the primary culprit and the one targeted by accountability processes
outside of someone just straight up embezzling funds or grossly misusing their power, organizations should also bear the brunt of the culpability especially when it relates to harms to the public good, especially if those harms benefit the organizations directly. and even in those cases the question becomes why weren't there accountability practices? checks on power? etc
I would still bet they aren’t making any money from data leaking to advertisers
