Conclusion
----------
The people behind ES5 have intentionally added malicious code to ES5. If
you have followed the ES5 discussions on message boards and read what the
ES5 people have said and done (eg. DoS attacking BitTorrent sites), this
comes as no surprise. The question then is "why did they do it?" I'm sure
they won't tell us, but here's a theory: They could be working for the
RIAA, MPAA, or a similar organization. Once they have enough users on their
ES5 network, they would start deleting all copyrighted files they own which
their users are sharing. The users wouldn't know what hit them.
