Adblock: Google did not slow down and lag YouTube performance with ad blocker on - Neowin::According to several user reports online, Google was apparently slowing YouTube down if it detected adblockers. However, Adblock has now confirmed that such is not the case at all.
ABP has that stinky practice of marking ads as “acceptable” (basically those companies pay ABP to be on their “allowlist”).
As has already been mentioned - stop using ABP, and use uBO instead. It’s a lifesaver.
