What users want?
GDPR allows you explicitly to serve strictly necessary cookies
without asking for consent. You only have to ask if you track people or don’t know what cookies your site stores with your users.
It is 2020 and totally possible to create websites without cookies or with only functionally needed cookies. You do your users a favour and your site will look better.
The very idea of the GDPR wasn’t to force websites to display cookie banners. It was to clarify that cookies can contain identifyable personal data and can be used for tracking, which is why we should avoid using them in that way or ask for consent if it really must be used.
