Besides a few payment processors, any evidence to support such claims?
afaik from those pools, exchanges, payment processors that went public pretty much all supported 2MB. the bitcoin-economy seems to be pretty decided on that matter. i obv wont go and search for every statement, i remember a dicussion at #bitcoin-dev where core devs also agreed that the economy seems to be against them. they blamed it on wrong communications etc.
or in other words, name important players of the bitcoin economy which publicly declared that they wanna keep 1MB. you wont find any.
As far as I can tell most users are divided and evidenced by the fact that bitcointalk.org and r/bitcoin have much more activity than other subreddits and forums there is some slight evidence that there are more in favor or Core's proposal.
to take the activity of btct and r/bitcoin as evidence is a non-argument as its obv that the community has a big lag in switching the places were everybody meets. a much better argument is indeed to look what actually happens on those sites! reddit is a perfect example, whenever a 2MB proposal made it through censorship a few hours it was massively upvoted. especially before r/btc came into play and took away some of its users. so as long as everybody was forced to use r/bitcoin 2MB had HUGE support. at least as long as you take upvotes into account.
here at btct is seems similar, imo 2MB is favorised big time. lets try a survey on that matter. i am willing to bet 1BTC that 2MB will be in big favor...
Looks like most of the payment processors genuinely support Classic and larger blocks but that makes perfect sense being that they principally care about bitcoin being a payment rails system and would benefit if nodes dropped off and where only maintained by them and exchanges.
PP play an important part in the economy, to just wipe them away as unimportant seems a bad idea.
Exchanges appear split but we haven't heard from all of them.
split? afaik not one exchange seems to favor 1MB. we had several announcements an they all declared to welcome 2MB.
As far as large investors are concerned , Classic has a few, but most appear to support core's proposal. (Keep in mind that individuals like Core Dev's , theymos, ect... have a ton of coins)
to look just for "large investors" seems incomplete thinking to me. why not go one step further and ask "what do stakeholders want?" we can only guess about that, but as i see the support in the community be it reddit, btct, blogs etc i see (like i said) the community wants 2MB.
that impression is further strengthened as i read core developers complain that they are not willing to give in to technical inferior solutions just because the majority of the community wants that. that pretty much showed to me that the are aware of to be the minority, but dont wanna let the "mob" rule...
Nodes and mining pools clearly support Core
they have no choice to support 2MB yet.
A majority of all bitcoin developers support the Core Scalability proposal. https://bitcoin.org/en/bitcoin-core/capacity-increases
yes, they do. but have you been in contact with some of the devs surrounding core lately? many of them have absolutely no problem going with 2MB in case classic will gain majority. they seem much more pragmatic and less ideologized than the die hard group. it seems that basically gmax, luke and one or two others are the reason for this big clash. imo the roadmap is great. go for it! but add 2MB and everybody is happy again.
