The comment wasn't particularly unfriendly at all. It didn't contain any personal attacks or contentless bashing. Indeed, the comment did something valuable: identified a problem, and thoroughly described why it was a problem. If the only way some one can give usable problem analysis and criticism is by including suggested fixes, and delicately toning down the criticism, then far fewer people are going to be willing to expend enough effort to interact beyond meaningless cheerleaderism.
In fact, your suggestion of a different way to criticize comes across to me as incredibly condescending -- to both the commenter and the original author.
