Agreed, enthusiastically. Reading the original article, I went from knowing nothing at all about Rocketr to hating them on principle in no time at all. So much marketing crap, so little content. PG was right to avoid them.
What should actually be happening is constructive criticism and lessons for all of us to learn from. At least they tried, at least they put it out there for others to see. So they got it wrong, that's no reason to hate.
You know a better way to do what they did? Good, tell them, and us.
