Well, ZenBeam, the first one looks pretty standard to me (under “spacetime diagrams”), but the second one that looks like argyle, I can’t make heads nor tails of. Of course, it might help if the captions on it were readable.

I definitely agree that that page doesn’t exactly give the best explanation of black hole spacetime diagrams, but I’m not even going to attempt to do a better job here.
