Mark Cuban Faces Backlash for Questioning NBA Fans About Illegal Streaming

Celtics and Heat played Game 7 in Boston with a chance for Celtics to complete the first ever comeback from an 0-3 series deficit in NBA history.
Mark Cuban, Mavs owner, asked fans on Twitter who were watching the game on an illegal, pirated stream.
Cuban's tweet drew attention and mockery, with "Narc Cuban" trending on Twitter.
Cuban profits directly off of the NBA's broadcast deals and has a keen eye on how these playoffs are performing.
Cuban is one of the few who has reason to seek legal action against those who watch illegal streams.
