"Hey there Sanjay, that's a nice H1 visa you've got there. It would be a shame is something were to happen to it. Why don't you do us a favor and insert this innocuous-looking off-by-one bug into the next build."
By the way, it's my opinion it's quite possible this is happening to voting machines as well. Or even likely, given what we've learned of NSA's depravity.
We don't like it when politicians pass laws that duplicate or worsen existing laws for the same behavior when "on the internet," or when patents are given for normal everyday practices that happen to be "on the internet". So why do we care about a defamation case just because it is "on the internet?"
