The "GDPR haters" realize that this is the sort of thing it is meant to prevent. They probably want to see this kind of thing prevented too. But they also realize that intention is hard to codify in law, and when their concerns about an overly non-specific and broad legislation are dismissed with "well obviously the GDPR intends this and not that, it's such a straightforward legislation to read, anyone can understand it," it's easy to become a "hater" - because they realize that there is a lot of latitude in interpreting the law. It would be more constructive to try to understand the position of people you disagree with, instead of labeling them as "haters" - just because someone is critical of the GDPR doesn't mean they don't value privacy.
