The nitter thread shows the exact behaviour the article is complaining about, proving it right (at least the toned-down version). Highlighting the abusive behaviour of one person in the GOS project that actually does happen isn't an attack against GOS, and certainly not wrong.

It's exactly the problem: You have one bully here that claims everything criticizing his abhorent behaviour is a libelous attack, thus he attacks other people and projects that attack him, spinning substantiated criticism against him as "projects driving a campaign against GOS". And the Graphene followers believe him. It's absurd.
