What value do we create over any other existing icon source ? All appear to follow the freemium model, so you get shit for free, pay for the good stuff. This is a quick assessment - is there any set in there that is free, quality, and no attribution (huge overhead for any larger icon-based effort)?
OSE Premise: The world's only high quality icon set that is entirely in the public domain.
How is this supported? By the premise of being the best, with one time-per-year nag message to support it. All proceeds go to support the icons, and all extra revenue goes to providing education scholarships to OSE programs.
