It's centralization, in whatever form it is today. You claim Blockstream is the problem, but maybe in 5-10 years it will be another company.
hint: DCG
http://dcg.co/network/"DCG sits at the epicenter of the emerging ecosystem"
to name just a few:
btcc
blockstream
bloq(gavin and garzik)
bitpay
coinbase
coindesk
circle
yes i should be attacking DCG.. but its blockstream that has the biggest tie to bitcoin code changes (followed by BTCC advocating those changes)
they are the front line of the corporate centralist agenda
