I clicked "This is evil" although I think that is just partially correct. The problem with tracking is that it exploits functionality that wasn't intended to identify users. In context of reality it is very nice that the author even ponders about it. This is already less evil than what we can expect on the "modern" web, however nefarious and tricky the mechanism might be. But loading a resource for tracking IPs isn't really intrinsically evil.
