European law is a lot less precedence driven that common law (though it still is a bit), so why shouldn't we demand clear rules instead of dangerous vagueness?

European law is a lot less precedence driven that common law (though it still is a bit), so why shouldn't we demand clear rules instead of dangerous vagueness? And for a small open source project, a 500€ fine is enough to make development and publication unattractive, a percentage of a devs yearly income is painful, and tens of thousands of Euros would be dangerous to the long-term financial well-being of the developers. Even if the fines are a lot lower than 15M€, this proposal stays shit as written.
