I know Brian Jones (not well, but my school affiliates with his), and have trained with him.
From what I gather, the point he was trying to make is that he'd see some shady "rankings" by no-gi guys who decide they can just declare themselves black belts and start teaching, despite having no official lineage or certifications. He wasn't shitting on no-gi as a style. He actually does practice no-gi. The rant wasn't targeted to no-gi guys so much as it was non-legit guys...though, he probably should have worded it better.
He certainly wasn't targeting 10th Planet, who use a belt ranking system in no-gi. They actually have lineage and legitimacy in the BJJ community. That said, I don't know Brian that well, and haven't discussed this with him personally. I'm going by what he's posted on facebook and his website.
