lol
you have no clue.

next you will be telling me that the chinese do infact have a time machine went back and made hardware purely to attack software.

wake up to logic.
hardware came first,
new software came second
new software is not getting the appreciation
new software not active
new software has a flaw

you cant blame old hardware

TL:DR
how can summer 2015 hardware be exploiting autumn 2016 released software

secondly blockstream admit the going soft anyone canspend route was a backdoor to avoid node consensus

thirdly
actually you will find it is an anyonecanspend. which is why if segwit activates they have to PREVENT old nodes seeing unconfirmed segwit tx's and also prevent old nodes from mining blocks ontop of segwit,
and why the segwit keypair wallet is not active in any of the 0.13.X 0.14.x
and why even when segwit is activated the segwit keypair wallet wont be available instantly because they need to ensure the old nods are cut off from manipulating unconfirmed tx's by ensuring the network is tiered with segwit at the top.

atleast try to learn the finer details and stop just pushing the utopian 30 second sales pitch
