There is no such thing as an "economic majority". 95% of Bitcoin users don't care or are uneducated when it comes to the scaling debate. A handful of CEO's saying they support this or they support that, is nothing more than political gerrymandering that literally means nothing, unless they personally own large chunks of hashpower, That is.

No one is going  to use the UASF chain beyond a handful of crackpots, Blockstream shills and poor saps who got brainwashed over in the censored r/bitcoin forum. In other words, it is doomed to fail, especially when you consider that the chain with larger blocks is vastly superior in just about everyway, and it will have hashrate support... yeah, UASF is doomed.

Blathering on about an imaginary "economic majority" is laughable, it doesn't exist, your average Bitcoiner who doesn't give a shit will choose the chain with large blocks simply because it has more utility, lower fees, less congestion, etc. Meanwhile, the Segwit-UASF chain will have no hashpower, no immediate advantage over large blocks, and only a small handful of reddit users... thus exposing itself as nothing more than a half-witted astroturfing campaign which ultimately, ironically, only managed to accelerate the move towards Bigger Blocks, which is the exact opposite of what they wanted in the first place.

The small-blockers will continue to double down and double down and then double down again, even as 99% of the network upgrades to larger blocks. It's insane. But they brought this upon themselves.

They are certainly free to move to an altcoin, though. Maybe they should call it Segwit1MBforever coin. I'm sure it will do really well. They can market themselves to all the Alpaca farmers in Equador who's primary concern is whether or not they can run a full node with a Raspberry Pi in the middle of nowhere.
