Ok, I misremembered it says "pay" for the aggregate results, not sell.
Our DAP deployment is jointly run by Mozilla and ISRG. Privacy is lost if the two organizations collude to reveal individual values. We safeguard against this in several ways: trust in both organizations, joint agreements, and operational practices.
A full solution will require that advertisers — or their delegated measurement provider — receive reports from browsers, select a service, submit a batch of reports, and pay for the aggregation results, choosing from a list of approved operators.
For the trial, the results for each task will be sent to Mozilla’s telemetry systems, which will be used to access aggregated statistics.
So it doesn't say ISRG is going sell data, but the "full solution" will have other operators that get payed, i.e. they're going to sell the aggregate data. Also, they envision multiple such operators, all of which it seems need to be "trusted".

Instead of what? As I said, this is in addition to existing tracking, with some vague promise that if current tracking methods were banned or abandoned, this could be used instead. Except it's not getting banned (Mozilla is not going to out-lobby Google) or abandoned (market forces prevent that), and why oh why would I want some alternative way for ad companies to get my data in that situation anyway? Let them die.
Now if another person is going to repeat this nonsense talking point, which you have picked up strait from Mozilla's corporate PR, I'm going to lose my mind. Have some critical thinking skills. They are giving away your data right now and they give you nothing in return except a nonsense promise of a fairytale future.
Please I just want a browser that acts in the user's interest only, does not work with Meta on adtech, and does not think it's their duty to save the ad industry from itself.
