I read that somewhere, too.

What Steam/Valve practically demands is that other companies/services providing the given game, shall be barred from offering the same content and product at a lower price, which therefore prevents competing with Steam by more competitive pricing.

Since Steam only serves as kind of a reseller, but is not the manufacturer or rpeucer of the games, that indeed is unacceptable. They want to forbid their competitors to outbid them. It also aims at establishing kind of an non-allowed price fixing, probably violating anti-cartell laws.

That simply is a total and complete No-Go.
