This is all very interesting but does nothing to support what is basically a bunch of circumstancial evidences to yet again try to paint blockstream in a bad light.
You're right, it's all circumstantial - just like any conflict of interest doesn't necessarily imply an actual foul - yet it is a concern.
The Blockstream people have been trying to argue that it's not even a concern or possible worry.That's just plain wrong and we've been through that before.
