Litecoin holders don't control anything. Miners are the ones who are in control in PoW cryptos. That's why PoS cryptos are above PoW, because in PoS users are the ones who are in control, not miners. I don't want to picture users and miners as two opposing groups, but often they act just like that.
Yeah, but even just a public effort or something to voice concerns. But from what I've seen from the Litecoin community someone trying to voice honest concerns and push the coin forward would probably be labeled as a 'FUDder'.
I think even the idea that Litecoin should be improved is offensive to Litecoiners. Maybe their logic is: "we got this far doing nothing, it would be wrong to mess with a good thing!".
