Headline isn't misleading. AT&T/Verizon are telecom companies, as that is their primary business. Satellite qualifies as a cable co, because they make their money on TV service just like Comcast, TWC, et al. That title is spot on.
Really, though, the distinction is meaningless. The pertinent point is how many people are paying for TV. You're not "cutting the cord" if you switch to TV service through a telecom. Still a net loss even with the telecom adds, but not as spectacular as without.
