Do you have a reference for the fines? Can't find much on the enforcement tracker [1], but seeing if the decision is about a nag or not is not easy to see quickly, so I may have missed them. NOYB also gave them a "grace period" before filing complaints, so I don't know how many complaints they actually made.
A lot of the nags have indeed gotten less illegal lately. Although I have very little faith in that even clicking Reject All really prevents tracking and selling me out. There are still those "legitimate interests" etc loopholes. And probably no regulator actually checks that the Reject is honored at all. Nowadays I don't even care. Used to go private mode for those but don't bother anymore. Hopefully at least my aggressive ad blocking makes spying on me mostly worthless on them.
Implementation of the GDPR consent was broken from the getgo (likely due to corruption). The spirit of the law is clearly that people shouldn't be tracked if they don't want it. Vast majority don't want to be tracked but vast majority are tracked.
If EU would have actually wanted this to work it would have been something like DNT. Also the promised megafines have not (and will not be) materialized and the (widespread and blantant) violations are at best just cost of doing business.
But making an actually effective implementation would have closed many revolving doors and fancy dinners.
Sorry for being so negative on this but I think entertaining hopes for such a fundamentally broken system may prevent less broken ones from arising.
