I understand the need to disclose sponsored content. Or if the manufacturer had veto-power or any say in the content.
I even understand that it is good to tell if the product was given for free or the trip was paid, even when they had no say in the content.
But I don't understand why anyone would need "I use affiliate links" caveats. This is useless info wasting space and reading time akin to "this website displays ads in order to stay alive". What does writing this (otherwise observable facts) actually accomplishes? What benefits does it bring?
