TRON is a rip off of IPFS, and everybody knows that (Source, in case you forgot: https://twitter.com/juanbenet/status/950142785373405184 )
I mean, the homepage ( http://tron.network ) has a giant face of the "Founder" / "CEO" of the company... Glorious.
I am dropping my 50 cents here: I would not look at it as if Tron bought BitTorrent... I think it was the other way around: BitTorrent was financially known to not be very "healthy". I bet it was more BitTorrent looking for mo-mo-mo-money as a valid exit!
