Yes, I know the reason why it was taken down. It's a bit of a private reason but we all agreed to have it no longer be available for purchase on Steam. Both Bloody Vulpine-published collections were taken down after Bloody Vulpine ended. However, Bodhi 'n' Friends is still available for purchase on Steam.
I'm not sure what other games have been re-uploaded, but as you mentioned, Make Beautiful is available on Steam via Vlad's game collection.
