By definition, anonymized data can not be reversed. However, many people do not know that difference. If the data would really be anonymized, it would be fine from a data protection point of view.

Legitimate interest is a way for the vendors to not need your confirmation. In general, your right to privacy is valued against the vendor’s right to operate. The most often used example is advertisement: in general, vendors are allowed to advertise, as they want to operate and sell their products. But you have a right to your data (e.g. mail adress, home adress, interests…). So courts have to value what is more important. Another example that most people would agree is that clubs want to show what happens in the club, so they publish pictures from their activities (interest of club to show they are active vs personal right to your image). As not every case goes to court, most vendors see their interest as more important and interpret “legitimate” interest rather loosely. So in general, the idea of legitimate interest is compliant with the GDPR, although I believe most sites use it too liberal.

That would be another option and a win-win scenario, I like it.

I think one thing that is often overlooked is supporting a good idea. I heard/read often enough that people like the ability to repair or tweak their laptops so maybe this is another reason to buy one. In the hope, that the company delivers more and better in the future.

This one is great! Made me think way too much
