So how valuable would it be to you if I would share with you that I spent $20 yesterday on shopping groceries. Probably not so much. But if I would share with you 90% of my spending, you might be able to infer a lot more information about me.

So the question isn't how useful the single request is, but rather what can be done with a lot of these requests. And Google and Facebook are specialists in generating lots of said requests with services like google fonts and like-buttons. And once you realize that the sum of these requests is so valuable that they are considered personal information, you want to protect them with laws.

These laws, like the GDPR, are already in place and this is one of the instances where someone didn't respect such a law. So you can argue now, that this single request isn't so valuable, but isn't that true for every penny of a million dollars?
