Quote from the article (includes a pool operator that also runs a large Chia pool)
Part of the chain split was attributable to a handful of powerful miners continuing to use the faulty Go client, including Flexpool, BTC.com and Binance.
And yes, I know this is an Ethereum issue, but if the pool operator can’t keep their software up-to-date for that coin, it just questions their ability to keep things running smoothly.
generally speaking yes, but it also seems the software provider is trying to cover their own ass here.
I’m saying that because so many nodes, including a few big ones with good reputation didn’t switch yet think there is a bit more going on then just operators forgetting to update.
(disclosure for the record I am mining ETH with them)
