Everyone thinks their ideas are brilliant and that the ideas that run contrary to theirs are terrible. Your comment is tantamount to saying "I disagree with these ideas".
That is not true. Other people can have good ideas, bad ideas, kind of bad ideas, very bad ideas, terrible ideas and off the chart stupid ideas.
So, no the comment is not tantamount to saying "I disagree with these ideas". It is possible to disagree with an idea that is not horribly bad. It is possible to disagree with an idea that is quite smart, just with a trade off I dont prefer.
I agree with your sentiment, but something this big should have been run through a committee of not-yes-men before publishing. I feel like honest feedback would have stopped this.
