This. I think the author of the article is actually using dismissiveness as a device to disarm people. If he downplays it people perhaps won't feel as threatened. "It's crazy" but maybe it's true.
I would like some confirmation though that there really is NO other evidence of dark matter.
Perhaps even if this theory doesn't stand the test of time, it will highlight the actual reasons dark matter has grown to become so accepted in our understanding of galactic mechanics.
Even though this story posits a 0-day in OpenSSH as the culprit, I'm of the mind that free software with a strong patch and update system is as good as it gets. If you don't update your systems say because you don't want to break stuff, sorry but even non-0-days will bring you down. So on the sysadmin side, we're moving toward more specialization.
