You probably can't definitively say they don't just by isolated checking. There could be a lot at play here. Maybe they turned it off while the heat is on, maybe whatever affiliate you were looking at didn't actually have a matching affiliate link on their side. Maybe there's an a/b test where they only jack a certain percentage.

When Linus Tech Tips first took them out as a sponsor they didn't appear to be jacking then either. But it would be very simple to build a system that turned link jacking off for certain users or during certain times or at certain thresholds.

Brave got caught doing it, and then stopped because the backlash was going to be worse than the advantage. Brave still had plenty of other ways to make money via search, selling advertising and BAT. I honestly don't fault brave for trying that because they are funding significant development to block ads.

Honey's base business model probably falls apart without some linkjacking. You go to a website to buy something and it says no no go buy it from these people instead. They've got to have it a lower price still have enough margin to sell it to you at that price, and pay honey for the redirection. It's kind of a sales worst case dilemma.
