Recent Utilisation of payment processors to enforce opinionated moral guidelines on Steam and Itch has been broadly organised by Collective Shout, but their members have been involved in many similar instances of smaller scopes.
The movement seems to have a strong Christian connection, as well as ties within the Australian Government, which suggests that this may be a component of the orginal Christian moral panic movement from the mid 2000s using a different lever (feminism) to the same effect.
The movement has been claimed to not be particularly "grassroots" due to its governement connections, but my findings don't really suggest that.
There are some quite queer bedfellows within the org that don't seem like they would exist together harmoniously, particularly the pairing of fringe femininism with Christian dogma.
