The OP was being shoddy by starting off with the one thing in the article wasn't inaccurate - the attack really involved a man-the-middle strategy, just one that also involved BGP hijacking. If the OP hadn't started that way, it would have easier to "hear" the point about the next few rather egregious lines:
"And for years it[either man-in-the-middle or BGP attacks] has been understood to be possible in theory, but never seen in practice[!?!]. That changed earlier this year when someone — it’s unclear who — diverted Internet traffic from some 150 cities around the world through networks in Belarus and Iceland."
It is worth noting how wrong that is but being accurate when you point to someone else's wrong stuff is one of the first principles.
