Please don't post shallow dismissals or take HN threads into flamewar.
The GP comment is actually a string of internet clichés: (1) "it's not some conspiracy", (2) "if they could sell" (3) "if you think [...] you should". That plus the confrontational edge makes it a flamewar comment. We're trying to avoid those here.
Btw, one key thing to look for is whether a comment engages anything specific in an article, or is just using it to make a generic point. The latter is always a bad sign in HN threads.
You only do that on certain topics.
