We are talking about what TTD does, which is place an ID cookie on a web browser that is a random and anonymously generated cookie, and what they collect with that, which contains no PII. That collection of all non identifiable information is owned and maintained by TTD and is only connected to a completely unidentifiable ID.
Here’s TTd privacy policy if anybody wants more info or has concerns about this technology and TTDs policy.

The Trade Desk bears no responsibility for how Nike collects and shares whatever data they have acquired and how they chose to share or not share that data with a third party.
I have no idea if Nike ever provides any PII to TTD. But that is Nike’s data and their responsibility. TTD doesn’t collect or use PII in the process of what they do.
