I wouldn't place too much emphasis on this. This has varied wildly.
Support for SW's activation on Bitcoin in the last 144 blocks (at this point in time) is only 30%.
Where is 30%? Link please?
Segwit support is now 58%
http://litecoinblockhalf.com/segwit.phpOn his defense maybe it got bigger in time between his post and your post. It is at 57% for now for me for example.
I think there is a big chance the segwit gets accepted, it will be amazing for testing out part, it will be like beta for bitcoin. If Litecoin uses segwit and overcomes every trouble and makes it work, than Bitcoin may follow.
