Well the biggest snag in the plan was that the hardcore big blockers had already moved over to Bitcoin Cash, so we lost our biggest support group early on.
Now, after segwit2X has failed and proved that it isn't likely to succeed any time in the next X years, well us segwit2Xer moderates have joined the bitcoin cash people (as well as some have moved to ethereum).
That community is much stronger and we are able to survive because it was a hardfork.
Lite coin has zero community of note. It is mostly just speculators, and people who suck up to the bitcoin Core team.
There frankly isn't even a litecoin vision. Like what do litecoin supporters even believe? What even IS a litecoin supporter?
I go to a bunch in person crytocurrencies and talk to people. And I can't think of a single time someone has said "oh, I am really excited about LTC" or similar.
Nobody is going out to coffee shops and saying "hey, do you accept litecoin?". Nobody is hosting litecoin meetups or tech talks or anything at all.
My biggest problem with litecoin, though, is that it is an unthreatening, PC, coin that has no intention of shaking the status quo, pushing the needle, or doing anything groundbreaking that might upset the powers that be in the cryto space.
If you aren't making anyone mad, then you probably aren't doing anything interesting or important. And I can tell you that nobody is 'mad' at litecoin.
