If you lift under the ball joint it puts all the weight and stress on the end of the arm, which it can tolerate. Put it under the middle and it will bend because all the weight is on the end, but the jack acts as a fulcrum point and the arm is not designed to be stressed laterally, as I said. It's not a load bearing structure because the weight of the car is normally borne by the top of the strut tower, the lower arm on a strut suspension merely provides radius and a place for the ball joint...there is no vehicle weight carried by it.
The weakness through the middle is why they fold so readily when curb checked hard...they aren't made to carry load in that direction...

I have personally learned the hard way. I knew before hand, but was rushing and I didn't correct my hoist position on the car, put it up, and noticed I damaged them. They can be damaged for sure.
