I trust Google ad monopoly to keep my data actually secure. They have a great track record of not sharing their datasets with anyone because this gives them an edge pushing ads down people throats. Google is honest about what they doing. Google also not going away anytime soon so they also not going to sell off their datasets to highest bidder.
And I don't trust Sam Altman and AI.com at all since their whole thing was built on lies. They could start regaining the trust by changing their company name.

It's not just about protecting data in the old sense - typically from other corporate entities. It would suck if your information somehow made it into a generally available model that then leaked some of that anyone asking a question
