I wonder what websites think of this toolbar stealing affiliate links from people doing all the work of promoting their prices. I wonder if Honey goes even further and turns vanilla purchases into affiliate purchases, actively stealing actual money from the site. If I were NewEgg or whoever else Honey has created affiliate links with, I think I'd be banning their affiliate account right now, or throwing in some captchas so their link theft doesn't work any more.
This only works if the store is in cahoots with Honey and only if they have coupons floating around that people otherwise avail of and only if they want to seriously piss off the people driving actual traffic to their store by letting Honey steal their commission.
The reality is Honey is scamming everyone. Customers by hiding codes, affiliates by stealing their commission and stores by parasitically skimming affiliate payments for no work. It may be Honey has a shakedown "pay us to make coupons go away" but the reality is stores could simply not issue heavy discount coupons if they're worried about that being an issue. Honey is required by nobody and given their parasitic & thieving nature I think they're going to be on the end of some lawsuits.
