That's not true - plain and simple. The theme is intuitive for anybody who can use WordPress. And I try to answer all genuine support questions (not related to modifications or third-party plugins) here.
You can see that I offer free access to documentation for my other 3 free themes. The goal is to eliminate entirely the need of support.
And two of those themes - Ascetica and Origin, don't even need documentation. Just like TwentyTwelve doesn't come packed with docs explaining how to use it in great detail.
The paid support option for Ascetica is absolutely optional and is mainly aimed at developers who want to use it as a base for their development purposes. Also, I have zero commercial interest there - I made the theme as a "Thank You" to the ThemeHybrid community.
Finally, Ascetica is one of my favorite themes and I am immensely proud of it. It is better than 95+% of the paid "premium" blogging/photoblogging themes. I have enough experience on the market to say that it would have been even more successful if I was selling it for $60. The mere fact that it's offered for free is the main reason some people perceive it as an inferior product.
