Didn't watch the video, but if replacing a referral code is wire fraud for depriving a content creator of money, then deleting a code is also fraud, which seems to imply that I, as an individual, can't edit out a referral code from a URL I receive. I think referral codes are a sales device and there's no guarantee that just because one sales person put in the effort of convincing a person to buy, it's still allowed for that person to buy from someone offering a cheaper price (which is what I gather Honey did by finding coupons).
