This can be a significant problem for those who use mining GPU. Network complexity will increase significantly and will make this method ineffective. The production capacity of Samsung is very great. They can significantly increase sales volumes of ASIC. This will cause a significant reduction in the profitability of mining. I think it's bad news.
Its only a problem to those pushing ASIC miners with ASICBoost. Jihan Wu is probably going to have a heart attack, and it serves him right - he's been a parasite on the back of Bitcoin for long enough. From purposefully mining empty blocks (contributing nothing back to the network, just grubbing for the block reward), to backing shitforks like BCash, he deserves a comeuppance from the juggernaut of Samsung.
As for it making GPU miners unprofitable, that ship sailed a LONG time ago for Bitcoin, on other coins that are "ASIC resistant", it won't matter too much either.
