Steam is currently being sued by Wolfire for being anti-competitive by allegedly having a "platform most-favored-nations" clause. Preventing games on other platforms from being priced lower.

According to the developer:

> [Valve] would remove Overgrowth from Steam if I allowed it to be sold at a lower price anywhere, even from my own website without Steam keys and without Steam’s DRM.

> I believe that other developers who charged lower prices on other stores have been contacted by Valve, telling them that their games will be removed from Steam if they did not raise their prices on competing stores.
