this is all because, if you have an idea/feature you want in bitcoin. you cannot just make a full node wallet and let it run and promote the community to run it too.
many have tried and the blockstream crew deem it an attack
blockstream deem only core can be the organisation that controls future features of bitcoin. and if you want your feature included in bitcoin this is the process you have to follow:
"People wishing to submit BIPs, first should propose their idea or document to the
bitcoin-dev@lists.linuxfoundation.org mailing list.
this mailing list is moderated by rusty russell - blockstream employee
"After discussion, please open a PR. After copy-editing and acceptance, it will be published here. [bitcoin BIPS on github]"
this bip listing is moderated by Luke Dashir - blockstream employee
if you want to discuss a feature on the development category of this forum, you will find it is moderated by gmaxwell - blockstream employee
as for the bitcoin code
the total rewrite of satoshi's code of 2009+.. to what became bitcoin core was done mainly by pieter wuille - blockstream employee
(sipa segwit core rewrite)
the ring network between pools (fibre) is managed by a version wrote by Matt Corallo - blockstream employee
the majority of the DNS seeds for the network are monitored by blockstream employees
seed.bitcoin.sipa.be
dnsseed.bluematt.me
dnsseed.bitcoin.dashjr.org
again if anyone was to dare make their own wallet with new features that are not aligned to the blockstream roadmap of 2015, is treated as an attack
this can be seen by how aggressive blockstream employees have been against xt, classic,unlimited, and many other full nodes that go against blockstreams roadmap
and yes i can predict alot of flaming from some who try their damned hardest to pigeon hole me into some altcoin camp.. yet cant deny the proof..
and yes some will try suggesting that matt corrallo and gmaxwell and luke JR are not employed by blockstream, but we all know thy are the founders of blockstream.. its an immutable truth even they cant rewrite
