Charlie Lee once said that all his LTC team had to do is wait and implement the good solutions from the Bitcoin developer team.
That statement alone should prove how completely worthless Litecoin is.
That's way too harsh. I'll have you know that some people actually find value in Litecoin, being a Bitcoin testnet and all. To each his own.
/sIf everyone were held to what they once said, we'd get nowhere. Litecoin has contributed a lot to Bitcoin as well, and in no small part due to the good relationships between the devs. Bitcoin may never have needed all that Lightning Network and atomic swap testing on Litecoin but I'm sure every success Litecoin's ever had was only good learning steps for Bitcoin.
Anyone can make a crypto... that's actually part of the beauty of Bitcoin. You're free to do as you wish with the code. Free to improve on it, change it, attempt to create your own value on it. Hundreds have tried, hundreds will continue to try. Whether they are successful or not doesn't matter. What matters is that they CAN try. How did something so amazing become something so negative?
