Here's what I posted on Moore's Google+ after the article. I also believe (even tho I love them) it is Automattic's fault to not come up with a Themeforest alternative...

(Comment on Moores post):
I think an issue with pricing comes with Themeforest's price dictation. Since Themeforest is so big now, it is difficult to price a theme higher. Ultimately I think it is Automattic's fault to not come up with a MarketPlace for Themes, similar to Envato's.
We both know that the problem and the money lies with people new to WordPress. They buy cheap, because they are not sure (and it's available cheaply). Bigger companies usually understand the value of their website and go with larger scale development agencies, whereas the smaller companies treat their web presence similarly to their plumbing and just go with the guy who offers it the cheapest, until they become big enough to understand the value of it.
Hope this makes sense, just my two cents...﻿
