Litecoin hashrate dropped ~20%, which I think explains the drop in the SegWit signaling:

They were able to move the price up by 200+% and the hashrate is up less then 30%.

So they are building a base of miners are profitable at the higher price thus encouraging signaling SegWit. Presumably that 20% hashrate will be turned back on when necessary to push the activation over 75%.

It is quite probable the Chinamen are simply manipulating the market and delaying SegWit on Litecoin in order to maximize their ability to profit on price manipulation. They can also use these resources gained from manipulation to buy more hashrate to signal for SegWit.

It is too much obfuscated to figure out. Bottom line is Bitcoin won't get scaling. Litecoin is poised to get scaling.
