whenever I hear from anyone saying "USE LN"
Whoever tells you to just use LN without warning you that LN is in testing mode, that it's risky to use LN and that you should really use LN for now only on testnet is incorrect (to say it nice).
I was also overconfident at some point and somebody shocked me telling that LN needs years to become commercially useful. Now I know that LN still needs tests and improvements. Badly.
On the other side, indeed, Franky is Bcash supporter and doesn't waste any opportunity to tell people how bad Bitcoin is. And while omitting that LN is early-beta, he will tell you (pretty correctly documented) all its flaws.
