Icetheme IT_newsy4 do I need to purchase easyblog in order to run it or are the free Module files you offer enough and I do not need to purchase easyblog?

So I purchased IT_Newsy4 Joomla theme from Icetheme.com. Now for it to run like in the Demo I would need easyblog, but as far as i am aware the files you offer under Free Modules are enough to get it to run like I want it. Do I have to purchase easyblog subscription or are the Free Modules truly free to use for me on a website?
