I'm not certain this is the right change. I'll explain how I got here so the rest of the task force can suggest a better improvement.
I was trying to explain what "minimize" meant in the first principle. Someone who's not already familiar with "data minimization" wouldn't know how much to minimize data or when it's ok to stop. The definition at https://edps.europa.eu/data-protection/data-protection/glossary/d_en says to "limit the collection of personal information to what is directly relevant and necessary to accomplish a specified purpose.", so I could just use "specified purpose" in this text, but that purpose could be spying on users, so I think it's not what the task force has in mind. "necessary to achieve their users' goals and interests" matches the direction we've gone in the rest of the document. There might be good reasons for sites to break this rule sometimes, but that's why it's a "should".
Once we have that, the third principle says almost the same thing as the first, so it seems mergeable. We lose the "in maintaining duties of protection, discretion, and loyalty" part, but this is the only principle with that sort of introduction, and nothing here makes https://w3ctag.github.io/privacy-principles/#user-agents less applicable. I've also lost some precision, but I'm happy to take suggestions for what to add back to the general principle.
