People have been trying to denounce the role of Collective Shout for weeks, even longer. This group has been under the radar till now, and if I'm not wrong even a recent article about them has been deleted.
Itch.io in their statement named them directly. They are now on twt lockdown and on the radar of every person interested in games or even censorship. A Japanese politician (/zkurishi, apologies I've been writing this on phone and could not translate the full name so this is their account) is collecting information about them, publishers are offering a hand to publish BL games (jast blue) etc.
