Its not. I have had honey installed on a separate chrome instance (mainly use FF). I was not aware that the extension pulled this, otherwise I would have never used it. There are some creators I follow, whose advice I somewhat trust and I have used their affiliate links to purchase a product. I want that creator to get the commission because they sold me on the product, not honey.
Also, just because something is standard industry practice, doesn't somehow make this behaviour any less egregious.
