Joking apart, aircraft are light because they only have strength in the areas actually required and in the direction of the forces. So a strut like this has to support a compression load of the wing and full fuel on the ground, and a tension load of half the airceaft total weight in the air, (increased by the angle of the strut).

There will not necessarily be much strength in a sideways direction, e.g. to support a person standing on it, unless it has been designed to do so.

Is this repair an attempt at humor? Or is it known if it flew like this?

I'm quite happy to stand on the strut of any Cessna with a FOOTREST provided by the manufacturer.
This one is bent UP so impossible for a heavy foot to bend it like that.
From an engineer's point of view, calculating the stress from standing on the strut is kinda simple. Remember there will be minimal dynamic load or factor of safety considerations.
