"Pertains" is doing a lot of work in your argument, and you're using it wrong. The data about who viewed your profile pertains to you from the moment the visit happens. That's what that word means, so your first statement is false.

The other important detail is that LinkedIn already has processed this data that definitely pertains to you, whether you paid for it or not, and are trying to sell it to you. In fact, to quote the article, LinkedIn's argument for not giving it to the user is "on the grounds that protecting that data took precedence". LinkedIn isn't withholding viewer data to protect viewer privacy. We know this because they sell it. If the viewer's privacy interest were so compelling that it overrides your Article 15 right (which is what Noyb is referring to), it would also be compelling enough to prevent LinkedIn from selling that same data to Premium subscribers.

The argument being made for this specific feature (not the ones you added) is that you can't simultaneously claim the data is too privacy-sensitive to disclose under GDPR and then sell it as a product feature
