One thing to realize is that Notch really never had any plans of making a VR port of Minecraft. In the past, he has stated that because of the JAVA technology used in Minecraft, it was too difficult to do it right, and they were having a problem making the UI work. They weren't very thrilled with the way the Minecrift mod did it, and wanted to do it better, but it just wasn't possible.
(In fact, the Minecrift mod doesn't even work with anything higher than 1.6, which means you can only use it in singleplayer or on servers that never upgraded. This is because of how much things have changed in the code between 1.6 and 1.7.)
So, Notch actually abandoned the effort sometime last year.
Last year: "We aren't making a Rift port because it's just too difficult with our current codebase."
Yesterday: "We aren't making a Rift port because Facebook."
To me, it sounds like a convenient excuse to cover up the fact that their codebase is really messy and can't do as much as they wish it could. We can blame it on Zuck now!
Except Tiny Tower plays differently and has different game mechanics than SimTower. But you're right, they LOOK the same. But that's about it.
I am going to make the assumption that you are living in the US (based on your other posts.)
Considering that the summary says that "UK Physicists" are researching this, my guess is that neither you nor I are paying for this as a US taxpayer.
I imagine publishers that make their living selling downloadable games on PSN suffered from this outage in a highly economic way.
If you have a procedure with 10 parameters, you probably missed some.
