Didn't Bitmain themselves confirm their chips support ASICBoost? I mean, they do hold a patent for it ... and tested it. So...
But, sure, that's not proof they've been _using_ covert ASICBOOST on mainnet.
We'll see what happens when the patch gets pushed through that fixes covert ASICBOOST. If Bitmain complains about it, or suddenly their economic strength weakens, then, well...

Yeah ... it's a shame I never pivoted our company into developing ASICs. Would have been nice to have another non-scam company in the mix, but ... such as it is. Nowadays I'd have go raise an order of magnitude more money to get started :/
