Given the subject matter of the article, that may be an unwarranted assumption.
Affiliate link defenders: Imagine this scenario. One of your family members or a close friend has been sending you "links to a few cool/funny sites" every few weeks for the last 5 years. Your friend can find such great web sites! That last one with cats swimming in a pool was hilarious! Then all of a sudden you learn that all this time he was getting paid every time you clicked on one of those links, but never disclosed this to you. Wouldn't you feel like that was just a tiny bit sleazy?
I don't think it's weird in any way to value one's privacy. This is shady stuff because 1. it leaks personal information and 2. most people don't know it happens and 3. they would have to actively take countermeasures to stop it.
That's not a bad idea. I'll make a note to check into that. Cheers
