It’s also a remarkably stupid implementation. If you follow the rules [1] in a strict way, the website should be usable if the user denied consent to non-essential cookie usage. You don’t need consent for strictly necessary cookies.
So a bunch of websites don’t actually need a cookie banner, as long as they’re not using non-essential cookies. You could easily get consent for marketing/tracking cookies in an unobtrusive way.
Instead, a lot of websites must have seen a drop in conversion because no one wants to interact with these awful cookie popups that have a hundred toggles.
AFAIK the page-blocking cookie banners don’t just convert worse, they’re actually not permitted (you can’t block the experience to force consent).
On my end: unless your website is very important to me, I’ll just refuse the cookies or hit the back button and load the next search result.
