lol, I love how the security of it all boils down to "trust that the authorities will make the right decision". Decentralized!
Firstly emergent consensus is a big part of decentralized systems. Core providers convening on a decision and supporting it is perfectly healthy. That’s quite different than a CEO saying things will be X way and everyone just having to accept it.
Additionally, my point is that people WILL likely try to have a contentious chain (as is their right in a decentralized project), but due to the maturity of Ethereum the technical consequences are much more impactful than the BTC/BCH scenario.
More decentra-lies and Ethereum pumping each other's, VCs and investors bags.
