Note he said most businesses are looking for Segwit activation + a hard fork blocksize increase (ours included). The "Chinese miners" have expressed that desire as well. Segwit is stalling because it's not what the market is asking for.
Many of the businesses in that list that preparing for Segwit, but would still prefer that scenario as well (including many of those with the largest user bases).
Lastly, I'm in the technical bitcoin community. I agree most of us are in support of Segwit- just the show of hands at Satoshi Roundtable this year made that clear- but many of us would also like to see a block size increase, and the dev / miner impasse ended.
EDIT: Segwit signalling by miners is currently < 25%. https://blockchain.info/charts/bip-9-segwit
Clearly, politics won't be ignored- or Segwit would be on track for activation.
Segwit never getting activated may even be a good thing. It will show everyone that Bitcoin has crystalized and can never be changed via petty human emotion. This was always Bitcoin's true selling point and we may be about to demonstrate it.
So yes, politics can and will be ignored.
But that's not politics being ignored- this is still a group of humans who couldn't come to an agreement after much politicking. That's politics being exhausted.
I do share your optimism that we have a system that can survive gridlock. It just won't fulfill much of its early promise.
They've stopped all important changes that people are asking for, so now the shoe is on the other foot.
Play stupid games win stupid prizes. The core devs will get nothing unless they compromise.
