Most CRDTs (last-write-wins being one of them) will result in a terrible user experience, and nobody would want to use it for collaboration. That's why most of these collab systems use OT, which is not trivial to implement.

Both CRDTs and OTs are broken. If you wrote them on your own, it's always "the next fixed bug will finally make it work!".
