While I agree with the spirit of your post, let us step back and think clearly about where your criticism lies.
Think about what it means to "hack" on something.
Today we often use the term to describe a programmer working feverishly on his software project "hacking away".
But based on your use of the term ("growth-hacking") we can see that it can often be used in the sense of hacking a problem into something more manageable. Jury-rigging, taking a smart shortcut, duct taping things together. Working smart, not hard [1]. Is that not what most of the people here are aiming to do?
So let's not get offended that someone else's hack is different from your own.
You admit that selling is important, and yet a good solution "doesn't need marketing", because I suppose the product sells itself? This board is filled with hard-earned lessons from fellow hackers who had a great product but no market(ing), and ultimately failed.
This "ogo" product is certainly not getting revenue from day one.
