I love free Joomla themes and the people that provide them deserve to be applauded. Applauded because they could make money but instead they decide to give back.
Sure, some of them make money too and the commercial providers almost every time clearly put in several more hours and they always look better and you've got the support forums and all the help you'll need, but that shouldn't take away from what the free theme providers offer.
Free themes is what makes it possible for people to get started, to learn about Joomla and ultimately contribute to the community.
To top it all off, it's got support for MyBLog and JomComment from Azrul. What next, a theme for JomSocial?
