I don't think it's using "Most certainly" in the sense of "Most developers using Python use Python 3 for any new projects.", like you appear to be thinking it says.
Rather, it appears to be saying, "Without any doubt, if you're using Python use Python 3 for any new projects."
It appears to be a statement regarding the suitability of Python 3 for new projects, rather than some quantitative claim regarding the number of users of Python 3.
After it was released, it'd be only the early adopters for a couple years, then the major libraries would follow a few years after.

Facebook already made the change, but they're tech-forward.
