I thought it was pretty well understood, to anybody paying attention at least, that there have been no official 6, 7, 8, or even 9G mobile networks yet, so of course 10G was a slightly quicker name for 10Gbps networking. It's maybe not an industry standard, but colloquially many datacenters will call a 10Gbps-capable network switch a "10G switch." This seems like an extension of that colloquialism to general consumers. But I guess I won't argue, necessarily, about being less vague in our choices of words for things. I just generally don't think accusations of "misleading" is completely fair, in this instance. Comcast has been misleading customers in other ways, but in this case, I think individual ignorance is doing a bit of the heavy lifting for the misleading here.
