The article states that Safari does have a limit of 50,000 rules, and that this is less than Google's updated proposed limit of 120,000 rules that ad blockers have stated is too low. I believe ad blockers like uBlock Origin also do some dynamic detection of behavior so that certain types of ad-serving that come from hosts you do not want to block. CBS Sports, for example, requires special handling -- in Google Chrome, accomplished by a separate extension for uBlock Origin -- to properly block ads on their site without destroying login and video functionality. This kind of blocking cannot be performed with host lists.
