Honey scam is a scam see megalag's expose they will actively lie to your face.

Bait and switch scam that steals affiliate codes and sales from sites. This is illegal and criminal.

For the user: this extension seemingly uses deceptive practices to offer inferior coupon, sometimes inputting their own brand coupon less than a discount than other coupons available while getting commission for theirs. Often, Honey declares no coupons are available even if the user suggests one to the Honey's database.
To other businesses: it steals from content creators or 3rd party websites who gain commissions when using their links when advertising/recommending by secretly swapping cookies at the last second before purchase. Either is does this by opening a quick pop-up window which it then closes before the user sees, or clicking the button "got it!" to dismiss the window Honey shows when it prompts that it doesnt have coupons available.
