Valve have added a new rule to the Onboarding guide for game developers, noting that payment processors get a say in what stays on Steam.
Newly added rule is:
Content that may violate the rules and standards set forth by Steam’s payment processors and related card networks and banks, or internet network providers. In particular, certain kinds of adult only content.

:/ payment processors strike again (slippery slope etc)
Every payment processor on steam is a publicly traded company, not privately owned. So it wouldn’t really be up to any one individual’s moral preference about such things. Personal preference would only count in to it if one of the shareholders had enough shares to push the board around, but the only one where I could see that being the case would be PayPal from people like Theil and Andreessen. Like they’re both jack wads for other beliefs, but I wouldn’t exactly call them bible thumpers.
