So either this was a security breach, a human mistake or a psyops/test on a small isolated American population.

In the first case, we'll probably only be told about it if they actually make an arrest and the system is patched.

The second is an interesting case, we'll come back to.

The final one: it was intentional and used to track what happened on the islands, and to also watch that information propagate back to the mainland. I feel like all of America has forgotten about PRISM/the NSA. With their immense data collection architectures and ties to large tech companies, they could easily filter the keywords and images they want, and get measurements of how quickly this information propagates and how people react.

Even more freaky, they can use language processing to even get numbers about what people might be feeling! I think we've all forgotten about this and it should be a chilling affect.

In the final case, we will, of course, never know. Anyone who suggests it will be called a conspiracy theorist (even though there is evidence the US government has preformed operations like this in the past, e.g. COINTELPRO) and the official line will be either reason 1 or 2 .. possibly with a patsy to arrest if need be. The truth will be declassified in 30~40 years so some people will be able to say "I told you so," but long beyond the time period anyone will actually care.
