If you look at the way things are going now, you might realize that miners have lost the plot.
I get where you're coming from... But there's multiple aspects of this whole thing.
I have my bias like anyone else but i'll just tell you what I think miners are thinking:
For one thing, a seeming majority of users wanted bigger blocks a long time ago
(and core never provided it so far). The miners do think they are doing what the market
wants.
Not everyone thinks segwit (or the core roadmap in general) is the way to go.
Even if some people like it in theory, for them it falls into the 'day late and
a dollar short' category. And it may not even activate... and Greg Maxwell
is saying that is just fine and dandy.
A lot of miners and users are upset with core. We see their actions as
stonewalling, or creating a problem on purpose so they can come in with
their solution. On the extreme end of the conspiracy theories,
some even believe that Blockstream is intentionally trying to destroy Bitcoin
because the banker-tied investors want that.
We can't let one small of group of developers stop us from scaling Bitcoin
in a timely manner. There is economic pressure because Bitcoin is already
losing market share to altcoins and can have its network effect eroded.
Congestion has already hurt Bitcoin's utility. Many feel that we cannot
wait any longer to get some relief in the way of scaling and that its
long overdue.
Some miners want bigger blocks but don't think EC is a great idea, others
do think it its a good idea.
BU is buggy but many just want EC from a variety of implementations.
Anyway i'm not saying i'm right because who cares who is wrong/right,
but just giving you the other side of the fence perspective.
Miners are not trying to destroy Bitcoin, they are trying to scale it.
My opinion.
We are not losing market share to Alt coins because of a possible hardfork, that is just the smoke screen for clever people to push stupid people to sell their Bitcoins and then to buy Alt coins the clever people have invested in prior to the hype. No matter what Alt coin you invest in now, miners will have a huge influence in the "politics" involved.
Asic manufacturers also have a huge hold over miners and what side they have to be on in this debate. Some miners wanted to give SegWit a chance on other Alt coins, to see what would happen and they were "influenced" by some of the bigger Asic manufacturers not to allow that. < Why? >
