Bitmain is announcing that if BIP148 succeeds, then they are essentially going to mine a new SHA-256 altcoin instead of Bitcoin. If you don't do anything, it'll be as if mining power dropped somewhat, but you'll otherwise be completely unaffected.

I feel like some people might read this statement as trying to force a decision between Bitmain's altcoin and BIP148, but you should be roughly equally unaffected whether or not you enforce BIP148. It might help BIP148's chances a little due to removing Bitmain from consideration and therefore increasing the chances of activating the traditional BIP141 SegWit deployment, though I continue to be pessimistic about BIP148's chances; I consider continuation of the status-quo and a somewhat later BIP149 UASF as the most likely outcome.

I kinda doubt that they're actually going to stick by what they say here, but if they do, it only seems like good news. If you'd like to use a currency controlled by a single company that puts its ability to use its patented Asicboost tech above all other considerations, feel free! I'll stick with Bitcoin, thank you very much.
