Fight for the Future digital rights group, the Blockchain Game Alliance and Enjin have all called out Valve for refusing to permit content related to cryptos or other nonfungible tokens on Steam Marketplace.

A letter open to all Published by Fight for the Future on Monday, the companies and projects are requesting Valve reverse its decision to “prohibit an entire category of software from the Steam platform” and take a chance on crypto and blockchain technology. Steam updated its onboarding process for partners on Oct. 14 to stipulate that no applications built on blockchain technology that “issue or allow exchange of cryptocurrencies or NFTs” would be permitted.
