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.
Stores your cookie preferences (so you won’t be asked again)
Cookie holding the user’s language selection
Cookie storing the user’s preference when in mobile but he desires to switch to desktop view
Cookies related to the expand/collapse state of panels
Cookie storing the user’s preferences on the activation/deactivation of experimental features
Cookie storing information on which experimental features the user has activated
We use these purely for internal research on how we can improve the service we provide for all our users.
The cookies simply assess how you interact with our website — as an anonymous user (the data gathered does not identify you personally).
Also, this data is not shared with any third parties or used for any other purpose. The anonymised statistics could be shared with contractors working on communication projects under contractual agreement with the Publications Office.
Given that that is the GDPR site, are they being overly strict in their own reading of the GDPR and the requirements for cookie consent?
But so am I. A cookie banner is asking clearance to store stuff in your browser right now and it's always tracking shit. Most of those at the top would be covered by "essential cookies" which explicitly lists appearance preferences. For more advanced stuff, which is usually SPA territory, the app can ask for your clearance when it's necessary e.g. "Save your session in your browser for later?" rather than some generic cookie banner shite.
