Keep telling yourself that until you actually believe it or tell that to someone that really cares about listening. He's trying to sell his post not a product most lower rank user do it, it's a little better than spamming. Merit is a motivation for them to contribute positively so if they're doing it right no problem. Was this a informative post? Yes. it hasn't been merited doesn't say otherwise.  Maybe next time you should concentrate more on the positive side of posts instead of criticising at every even opportunity.

Lol my bad didn't see the reference he gave, although I still benefited from the post. So I'm good
