I think you're justifying a really extreme reaction based on the worst behavior of a few companies. GDPR doesn't just go after data-resellers. It targets how a well-intended company can use and keep your data even with no third party involved.
Laws that mess up the good-guys lives are bad laws. GDPR is from the same folks who thought a law that lead to pestering users about cookies was a good idea.
Also I like the cookie idea. If only people really cared about misuse of their data they'd like it too. We've seen how good 3rd party cookies have been for some democracies.
>All well intentioned gun enthusiasts should support it.
Really black/white argument there which the issue is not. And nor is this topic. There should be more nuance in GDPR, but there isn't which creates a lot of discomfort.
>It's not stopping any well intended company from fairly using data.
It actually is, but whether or not that is an overall good thing is yet to be seen. Certainly, they did some level of testing before proceeding.
