Their comment seems much more directed at the incentives and outcomes of affiliate/content marketing than it does at you personally, so it’s weird to pretend it’s a personal attack.
Especially when you underscore the incentive issues with your closing question: if the only reason you can imagine going to the effort of a substantial review is financial incentive, that in itself is a pretty good criticism.
BOTH people are distorted by the wrong incentives.
It is NOT a question of being pedantic. They're literally not criticizing you when they criticize your incentives. I think this critique is from a board with relatively high percentage of systems-type thinkers.
