I haven't heard any accusations of him commiting a crime. It's not about if he's a criminal, it's about if he's a good person who people want to associate with. If someone's acting a fool, they're totally within their right to terminate their relationship with them. Itskull acted a fool and so the hermitcraft group decided to terminate their relationship with him. It's not hard to understand why they wouldn't want someone who's acting so incredibly unprofessional associated with their business. It's not "cancelling" or "cancel culture"
