Does Blockstream have all the power to control everything? No the miners have a big say on the whole thing. So if Blockstream turned out to be a bad player another group will try to fork BTC away from core with the full support of the miners. What are you afraid of?
Nobody on this side is scared of anything. ^smile^ We are saying quite the opposite, because nobody needs to be scared of Blockstream or
any other developer doing any kind of changes to the protocol. We have Peer review and a strong incentive for developers to be honest.
If the network of users < miners > or node hosts, find out that a developer is hiding some obscure agenda, then they have the most to loose. We have Alt coin developers and developers working on private blockchains, that would like Bitcoin to fail, and if Blockstream or any other developer fails, one of these entities will take their place or replace their code with something that are more desirable.
I say again, consensus means nothing, when consensus can again be used to replace undesirable code. This code might not even come from Blockstream developers. ^hmmmm^
