I think it's prudent to assume that these companies are selling your information to anyone with two nickels to rub together, regardless of which tech celebrities they are linked to.
Palantir is an integration company. There are plenty of data brokers to scrutinize. i.e. discord itself sells your data.
This is the part that loses me, my understanding was that this was only supposed to scan things offline, not collect any PII. Are they lying about not collecting the face scanned data?
This. The data collection is the product, that’s why it’s free.
