Unless I'm seeing things, there is a lot more to it than collapse on landing. In the second video it looks like there is significant damage at the inboard section of the right wing prior to landing.... can also be seen in the close up toward the end of the landing 'roll'.
Check at the 14 second mark and compare to before touchdown?
