>You also have to remember that tons of these regulations are vague and unclear and massively open to interpretation, and that companies can genuinely believe they are complying, and their lawyers agree, but then judges still rule otherwise, because it's ultimately just a matter of opinion because of the vagueness.

This is the equivalent of the famous Babbage anecdote, but for the law. That's absolutely not how the law or regulatory compliance works, not in Europe at least.

...but it absolutely is? Why do you think fines get appealed, and companies often win on appeal?

If there weren't vagueness and shades of gray, then appeals courts would barely need to exist.
