Welp, that's interesting. I see that Cobra has spent the last few months at the very least criticizing blockstream, sidechains and the lightning network very heavily.
I'm sure he won't be leaving bitcoin but as he says that he will be retiring the application, I suspect that he was sick and tired of being coerced to pick sides all the time. I'm sure many old timers in the bitcoin space would have an equally hard time in his place.

I'm not sure however if he'll be able to pass down his anti-blockstream sentiment down the line if he leaves. To be honest, I'm not even sure if Cobra's existing influence was enough to keep block stream from getting a firmer grasp over bitcoin. You can see more of Cobra's thoughts on the matter in an earlier comment he had made. Just food for thought...
