brg444, I'm past the part about core dev altcoin implementations. I do see how it would be a hard sell for them although not impossible to sell to noobs. You forget that we are witnessing the power of what they can do RIGHT NOW with this SC proposal. They've banded together precisely to push this proposal through as a for profit company which requires a fork for them to be successful. It's not a wild thought imagining them trying to implement a new currency some day. LukeJr has talked about demurrage coin on reddit. Why? I could see a day where he starts one on his own and claims its just him personally, not Blockstream. Unlikely but possible.
They have banded together because they believe this proposal adds considerable value to Bitcoin's infrastructure. Nothing more.
It is not a wild thought to imagine them try to implement a new coin. In fact they are free to do so. But as in all things alt coin, the free market will decide whether their proposition is worth switching over from Bitcoin. In the event this happens, their position as core developer would be of little help, if any at all. The whole idea of Bitcoin is that we do not care who created it, only that it works as advertised.
The agenda you are trying to push is they would somehow leverage their position in the community as a way to influence the market to switch over to their coin. Sure, the community would carefully consider the proposition considering their status. The code would be reviewed, analysed and criticized the same way Satoshi's was. And if it turns out there is any unethical concern comes up or it is made obvious this coin would provide unfair advantage to some entrenched interest then the idea would be dismissed and everyone would move on.
