Hmm…interesting. I would have figured it would be more akin mechanically speaking to being suffocated, as those scenarios also deprive the body of oxygen. Maybe the difference is that the action of breathing out and then breathing back in would be expelling any remaining oxygen from the lungs without replacing it with more oxygen?
I am having a hard time following how it renders immediate unconsciousness though, given that one could simply breathe out to empty their lungs and then hold their breath for a short period of time without being rendered unconscious, and in theory that should be comparable. Sounds like I might be missing something key here that likely accounts for the disconnect.
Full disclosure: Haven’t read the article yet.
Working in corporate IT, this most likely is targeted toward enterprise customers who either take a long time to roll out OS upgrades or can’t due to technical limitations within their environment. In those cases, paying the cost of extended support is more palatable to troubleshooting or rushing mass OS upgrades. This is a fairly common practice with enterprise software vendors.
Edit: Okay, just skimmed it. Looks like this is actually a new program for non-enterprise consumers, which is interesting. First I’ve heard of that.
