Hopefully it makes a real difference to compensate us for the never-ending, dark pattern cookie notices we have to endure as a result. Who wants a choice of 'Accept all' or 'Manage your settings' on every second webpage they land on?
Even Google of all places "respects" it now (after pressure). It becomes noticeably better every year.
GDPR may have had good outcomes too, and I am neutral on all other aspects, but whatever part of EU and California regulation led directly to cookie banners is a colossal failure which has benefitted no one (except possibly the dozens of snake oil cookie banner products which pretend to comply).
