Actually yes they do! I have a few symbol fonts in my library that cost way more than he's asking for the 4 weights.

My personal hesitation isn't due to paying for a symbol font...I'm waiting to see a bit more of the font so I can decide if the style is neutral enough that I'll be able to use it in enough places to make the cost worthwhile.

I don't think it's really paying for 'font' symbols but paying for something that's easily droppable in your HTML using <i> tags. At least that's why I use FontAwesome.
