The author is trolling with a bold statement (and attack on someone) without _any_ stated reasons. This is something which is not tolerated here.

Your first comment was not in line with HN guidelines. Your second comment is much better because it gives reasons.
I would have downvoted your first (and I do not work for GCP, mind you); I am now inclined not to just because you posted the reasons in your second comment.
