But is anybody really thinking that BU is anything else but an "I don't want Segwit" thing, in other words "I want to keep bitcoin exactly as it is, but I want to make you think that I want also a "solution" for crashing the lucrative fee market" ?
For some people it's:
I want Bitcoin to split in two, so I can 'double' my coins!
I hate the censorship theymos is doing on his privately owned forums, therefore I am going to express my anger of this by supporting BU
I think the devs have full control over Bitcoin and I trust the miners more than I trust the devs, so I want miners to have the power to make economic policy.
