There are three businesses involved. A 3rd party (eg YouTube reviewer) has their affiliate code stripped from the page, and as a result is losing out on income. That may be illegal. And the affiliate doesn’t have a business relationship with honey. They didn’t sign anything away with them.

Also honey was (until recently) marketing themselves as “we find you the best coupon code”. That was & is false advertising, since they were clearly hiding coupon codes they knew about when companies paid them to do so.
