> I'm asking "if cookie consent banners are the less than idea solution, why isn't the official EU government site implementing it in a way that is ideal?"
Cookie banners are perfectly valid solution to the problem. GP originally said that the ideal solution is to avoid cookie banners by not tracking users. Not that if you want to track users there is a better solution than presenting them with a cookie banner.
> If a company is deciding how to comply with the GDPR on its website, can it go wrong with copying how that site does it?
No, because that is how it is spelled out in the law. Rejecting tracking must be as simple as accepting it. On the EU website both those options are presented in a clear way.
> My claim that it isn't malicious compliance to use cookie consent banners, but rather the least risky approach since that is exactly how europa.eu complies with their own laws.
There is no malicious compliance. If it is done as it is done on the EU site then it is compliant. If it isn't then it is illegal. Malicious compliance means that the letter of the law is strictly followed so to cause/do something not intended by the law. In case of hiding the reject button, that is illegal.
