Seriously, SegWit has 100% signalling now - every pool is signalling it. I wish to see any code example instead of comparisons without any sense created by some Chinese miners so they can sell their version of Bitcoin to as many people as possible. But that's just my opinion. SegWit is working on Litecoin since few months by the way - no problems with it.

Also Bitcoin core is a team of over a hundred developers without any leadership - they protect the Bitcoin code. You can see what happens when other inexperienced devs try to crate their own Bitcoin - BTC1 unintentionally forked even their testnet...
