I would just call it "exclude red shields", and leave the definition up to you (even if at later points you decide to use different criteria for red shields). Right now you have some internal threshold, which seems fine.
And as for top 10,000 websites. I just typed in https://kagi.com/search?q=formula+1, and I see that sites like eurosport.com have 49 trackers enabled, while formula1.com itself manages just fine with 1 tracker.
I have no desire to go to sites that are just loaded up with trackers for no apparent reason.
