Now it doesn't matter, without f2pool it's impossible to get enough hashrate, SegWit on litecoin is also dead.
who said F2pool is not supporting SegWit anymore? do you have a reference or is it your guess?!!
as far as i know f2pool never said anything about not supporting it and the evidence shows they are supporting it.
i don't know where to see the blocks and where they add the string but the percentage is still between 68% and 70% and without F2pool that percentage would have dropped down to 50% at least and then went down back to 30%
Good news is, the price increase might not be dependent on that.
well yeah but it wasn't ineffective either.
EDIT:
i found it and yes F2POOL is still signalling SegWit:
