Those articles are describing a very different thing. Jon is not saying (or supporting your implied claim that) Mastodon is a white supremacist service, let alone a white-supremacist community. In fact, for both Lemmy and Mastodon, they praise the responses of staff to racist content. As far as I can tell, the closest is them saying that their broader society is white supremacist and that has systematic implications on Mastodon which typical users can be ignorant or dismissive of.
