What do you guys think? Is this anything to be concerned about?
there is not unless people will start supporting their blockchain projects too much at the expense of decentralization. I find it as a great news to seee the company like facebook joining the movement
That's what most concerns me- the VAST majority of people do not care one ounce about decentralisation, so when FB shows them their shiny new blockchain I think the hype and momentum there would be incredible.
I agree that more exposure is good for the blockchain movement overall, but it would be a shame to see some of the great decentralised current projects get displaced by corporate giants.
