So how valid is this stuff? Well, thanks to a reliable source, I've been able to confirm that ntkrnl is indeed connected to Microsoft, although I haven't been able to verify any of the poster's claims. Just because the leaker is in a position to know this information doesn't mean this information is true. (When I reached out this morning, Microsoft declined to comment.)
On top of all that, according to one person familiar with the situation who spoke to me under condition of anonymity, Microsoft is currently trying to track down and identify ntkrnl. According to that person, Microsoft executives are looking to take legal action against ntkrnl, which, again, doesn't mean that everything he says is true.
