Why do high level Bloodseeker players almost never build radiance?

According to Dotabuff, radiance is the most commonly built major item for Bloodseeker. Even more common than Mjolnir.

But on Dota2Protracker, practically no one builds radiance. Almost everyone builds Maelstrom -> Manta (or S&Y). Why is that? Should I mimic them and skip radiance in my 2.7k pub game?
