Everyone knows at this point that BIP110 was a failure and the majority of the supporters at the time have also backed away and accepted it. What seems to be left are people trying to make some short terms gains out of blake2b coin while it's easy to mine. When Bitcoin Cash forked off, in Nov 2017 it actually briefly surpassed the total mining hash power of the main BTC network, but then still failed longer term despite all sorts of other marketing efforts, such as promoting it as Bitcoin on Bitcoin dot com. Seems unlikely we will get anywhere near that kind of effort for Blake2b, which I think will just fizzle away alongside the opportunity to make money from it, much like any other shitcoin.
