> The GDPR's cookie consent was written far too broadly to the extent that any use of cookies - even if they don't track an identity - requires a cookie consent banner.

That is not true. Cookies that are essential to providing the service the user expects to not require a cookie banner. People just add them because they either can't be bothered to read the rules or because they are doing tracking and things the user does not want.

A cookie banner always means the site is trying to get your clearance to do something you probably don't want.
