The issue might be that a lot of websites are run by marketing and communications teams, that all have KPIs and metrics, which they need to track (sometimes for no good reason). Some of this could be done without cookies, but that requires an active operations team which can support it, but because these sites a managed solely by non-technical people they don't know what to ask for, they just know that if you slap on the snippet og JavaScript, they get the metrics they "need".

Github is probably the largest site that does not have a cookie banner, because they don't need on. If Github doesn't need a cookie banner, then maybe the EU commission could work on removing theirs as well.
