In some sense you are right - the article hasn't much useful criticism of Topics in comparison to FLoC (and the Brave plug at the end makes it read like an advertisement).

However I think the article is right in the sense that we shouldn't miss the forest for the trees. Image you were robbed and the robber suddenly asked if your issue with him could be solved if he only took half of what's in your wallet. Surely that would be an improvement but it doesn't solve the root issue of him robbing you in the first place.

In the same sense, I think pulling attention back to the fact that Google is building third-party tracking right into the browser - and also aggressively protecting the whole concept of tracking as some sort of fundamental necessity of the web - is justified.
