I firmly believe a money making venture will not shoot themselves in the face by destroying the network marketplace in which they are profiting and succeeding. There is no gain in destroying bitcoin now, unless they have some "counter agenda" that is as hilarious as hollywood or obamacare.
They are not a government, entertainment producer nor 'BigPharma.'
Just my 2 mbits.
Consider how this may not really be any better after all.
Having >50% of the hash power and pointing it to other pools simply means that they can point it back at will. Worse still they can in fact entice others to join ghash.io by artificially reducing their percentage by switching some to other pools and then switch back again anytime some shenanigans suits them.
By selling contracts, they have garnered this control.
The decentralized trustless network is becoming centralized and is now requiring trust. The erosion of some of the core merits of the bitcoin protocol is a serious matter. It is astounding that a summary report of an "internal investigation" is considered authoritative and exculpatory.
It merely stated that "it was the old guys, not us" and gave no new transparency or plan to change anything, no new controls implemented.
Miners, take a look at what you are doing and how, please. We are in your hands.
