I would say transparency is not the problem as much as a lack of accountability. They keep on doing things like this, and lying to congress and everyone else, but none of them are in jail or even afraid.
I know it is probably outside of the scope of this kind of oath, but I think there should be more work done to encourage publication of results that did NOT show what the researchers/scientists set out to. Negative results are being swept under the rug and ignored. This is a problem that really seems like it should be addressed.
Comcast actually WAS throttling Netflix. This was proven when people tested with direct connections to Netflix and saw issues, then used a VPN (still on top of their Comcast connection) to access Netflix, and saw no issues at all.
That is the clearest indication of direct interference with traffic as far as I am concerned. Remember, VPN traffic is encrypted, so Comcast can't tell what the termination point is.
