Graphene (more specifically its founder) is always in a vicious cycle of claiming that everyone asking for proof of Graphene being "under attack" is in itself making an "attack". You can consider yourself Graphene's enemy for life for your transgression.
Watching these youtube links makes you an attacker also, so be careful: https://youtu.be/Dx7CZ-2Bajg https://youtu.be/4To-F6W1NT0

I honestly don't know or care enough to figure out how much exaggeration is taking place, but it seems like there's at least a possibility that this is a nothingburger from a powerless journalist that's being extrapolated like crazy. There might be a definite answer in that thread but I don't have the time to evaluate all angles of this incident right now.
