Not even just questioning how referral links work, but questioning how a company makes money. I never looked into Honey, but since it wasn't obvious how they were making their money, I assumed it was something sketchy and stayed away from it. My assumption was it was the typical data harvesting and selling (once they had the extension in your browser they could track you). While I think the tracking/selling is immoral, what they did instead seems like fraud (IANAL).

I'm pretty surprised that so many YouTube creators pushed Honey without questioning how they were making money off giving away discounts. Did they not ask, or did Honey have a lie for that as well?

I guess they say it, but being owned by PayPal I'm guessing there was an assumption that the commissions weren't being stolen from other people, and the codes being provided were organic codes and not ones created for Honey by the merchant to manipulate the user into thinking they were getting the best deal, when they weren't.
