Them 2 unknown miners are truely running the network pretty much all other pools have stopped as of now
You have no idea who they are or if there is any alternative motive or why they continue to mine with huge power outperforming all the major big block supporters yet support them with adding value
This is very dangerous thing to do why do they have the need to hide their identity unless their is something there hiding from and dont want a manhunt against them if something bad happens
Bitcoin is a very private network and community. So there is no need and no force to show what you do and what you have. Sure we want to 'measure' decentralization as a factor of security, but even if you claim some name or pool mining label, we never can be sure if that is all true... So whats the point in having some names you cannot trust end of the day anyway? It just gives you false feelings...
