Which is bullshit because tables in a public space are abused.

I think the proof forgets that legs A and C are locked in a struggle over being on the ground. There is no guarantee that C is still on the ground when A touches.

I've had a great deal of luck getting the table to wobble less by turning it, but have also met with infrequent success. And square tables are more constrained to orientation.

For decades, I have been well known among my colleagues, friends and family for rotating tables any time there’s even the slightest wobble, not giving up until the deed is done, and nearly always doing so successfully unless a leg is clearly missing its foot. Most of them tolerate it.

This was my thought too. The other legs don’t just stay the same as you turn it. What if one of them is now off the ground or too far into the ground?

Isn't this a topology problem?

On an uneven surface, are there always 4 points that define a square of sides length x that are always [in the same plane]? That has to be no, right?
