The evidence is all the weird bits about how the paper was published, and other internet comments about the third author's relationship to the group.

The authorship of the papers is relevant to the science here, since both papers have quality issues, so I wrote out the accusation as best I understood it. The evidence is nowhere near enough to prove anything and largely rumor right now, but I do think it's suggestive.

The weird bit and internet comment do not corroborate e.g. your "without the agreement of the other two authors".
