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.
