'Thoughtfully curated' by whom? The user or Google? This seems like it's less about privacy and more about advertising. I wonder if it would have been more honest to call it Advertising Sandbox?

FTA, they're very clear about it being for advertising; just also with privacy in mind.

As long as the base list is relatively short, published, and no other data is sent; it probably doesn't matter.

If it's a long list, or changes a lot, then the concern that "Recent Abortion" or "Transitioning" or "Pregnant" or "BLM Activist" or "Trump Supporter" or ... will start to drift into the list if it's valuable enough.

You know it will though.

If I as a user had the ability to select the subset of the lists of interests and ensure that only those interest categories are ever signaled to a site then I'd almost be fine with Google's current proposal. However, we all know Google will most likely never allow end user control and will go to great lengths to obfuscate what data they are actually sending to sites.
