Since Litecoin is often looked as a Bitcoin testbed, they wonder if btc will soon activate segwit, though Bitcoin keeps meeting opposition from miners.
Jihan Wu was totally happy with SegWit during Litecoin's scaling conference and soon after AntPool switched started signalling SW.
It is not rocket science, is it? if the delay in implementing the Segwit causes a rise in the number of unconfirmed transactions, then obviously it is going to benefit the altcoins. So those who want the altcoins to rise will oppose the SegWit implementation for Bitcoin.
