You keep pretending to be great at assessing risks from your armchair but forget that these two guys are professionals, and you know nothing about rock climbing or this particular situation, you haven't provided a singke reason why what they are doing is risky, or stupid. Anchors not bomber proof enough? Not enough redundancy? Too much slack? What is the problem exactly?

Yet you feel entitled to judge them. These are probably the guys that come and rescue you, when you do something stupid in the outdoors, not the other way around.
