everyone has a reason want Lightening Network,including me.but Bitcoin is not belonging to one person or one group has a reason.
The Bitcoin Project does belong to one group: the dev team running the project. What I want, or you, or anybody else, is not going to change their minds.
only because the majority are fine with the current dev line up, especially merchants and chinese miners, but it may change in the future
You're right. But that was kind of what I meant by saying "the dev team running the project".
Forget the future, what about the past? That team changes every day, because anyone can submit a pull request to the code repo, and you can see that by looking at the statistics on Github; the same people working on Bitcoin 4 years ago aren't all working on it now. Some have gone, and other new faces have joined in. I wouldn't expect that to be any different in the future either.
i don't know right now, but there are miners and merchants among the core dev?
what if in the future the whole core dev is full of miners and merchants and they will work for their interest pretty much, it would be easy for them to dictate the progression of bitcoin in a chosen direction
