Yeah, it’s still confusing. It could be that since the ruling was made less than a month ago, there are active ad campaigns that they’re just going to let run their course, rather than cancel them.
But also, note the following from the source article:
Comcast said it may still use 10G in ways that are less likely to confuse consumers. "Consistent with the panel's recommendation... Comcast reserves the right to use the term '10G' or 'Xfinity 10G' in a manner that does not misleadingly describe the Xfinity network itself," the company said.
When contacted by Ars, a Comcast spokesperson said, "We disagree with the decision but are pleased that we have confirmed our continued use of 10G in advertising."
