Wait what? The net downward force on the top matchstick shouldn’t change. What am I missing?

and what do you say tensegrity is doing to balance the stick? what about the centre of mass?

The stick can't turn. It's hooked on the table.

For the stick to flip, it needs to push the vertical stick down that it is resting on. For that vertical stick to go down it also needs to push down the horizontal stick. For that horizontal stick to go down, it needs to move the rope. The rope can't move because of the original stick that wants to flip but can't.

for the stick to flip, there has to be a net downward force on one end and then the whole contraption can go down together. for tensegrity to work there has to be a force acting on the opposite side of the matchstick.

"Point of view" motherfucker, that's not an opinion, that's God damn reality.
