Nothing can travel faster than light through vacuum, so that bit is implied as well.
I disagree with their quibble about the title being intentionally misleading but, meh, I've picked stranger technically correct hills to die on, the rest of their comment is interesting, it's fine.
Arguably there's a lot of people who don't know nothing is faster than light in a vacuum.
Because of science fiction, and lack of education in much of the world (looking at you USA), the title can easily make certain people think we discovered new science that allows us to travel faster than light. Especially for folks who only look at headlines.
The whole thing is a silly quibble. But sensationalized headlines get better engagement, which we can all see here.
