Whatever technology they have their hands on is (probably) their big money maker. If not currently, with their uncounted billions (trillions?) in under the table money, then in the future when the technology is rolled out in production.
If they give anything up, it will be the smallest sliver of a token gesture that they can get away with. Do we really expect them to do any more than that?
I’m sure that, if they are feeling like the tide may turn against them, efforts are being made as I write this to move/hide whatever they have (even better than it’s currently being hidden).
So we may get some, minimal disclosure — to shut us up — but I doubt it will ever be “full disclosure”.
Even if NHI comes down en masse and holds their own press conference, the contractors still are going to hoard what they already have…because $.
