I like it.
And I think Archie and Lili sound lovely together for sibling names.
I actually like the fact they've stepped away from traditional rosy all names that come out over and over (they each have about 5 each!).
I also like that they have others such as Savannah, Lena, Mia, Isla, August and Lucas.
Lili does sound nice (spelt Lily it would have been better.)
It's the fact that they used the Queen's pet name - Lilibet - when they show such disdain towards the Royal family, and everything it represents, and wanted to distance themselves from it. (Well, until it suits them to be part of it...) 
They wanted it all. They wanted to be independent, and to not have to be arsed with Royal duties, but they wanted to keep the Royal titles. They were refused, and told 'you don't get to have it both ways; you're in or you're out.' They chose OUT ... (Well Meghan did as she dragged Harry across to America, 6000 miles away from his family and friends.)
They then said they want no publicity, but have pushed their face into - and ONTO - everything, then cried off when people try to report anything on them. They constantly complain about how awful we all are, and Meghan chucks in all sorts of nasty accusations against the Royal family, and Harry calls it a prison and a cult. Yet here they are using the Queen's pet name for their daughter's name!
Every day that passes, they get more ludicrous and dislikeable.
I agree with previous posters; it's massively attention seeking, almost the the point of being desperate. As I said earlier, they're the most irksome pair to ever emerge from the Royal Family. They are actually an utter embarrassment. I bet the Queen facepalms every time she hears their names mentioned.
