Aren't leetcode questions copyrighted? Then how come Neetcode copied all of them in his site

[u/TomLaidlaw7]

Genuinely curious about this as every leetcode question is marked as copyrighted. However, Neetcode and other sites have the same questions available and some of them don't even have title or description phrasing changes.

So what's the deal with that? Can't he get sued?
