Posidrive is not that common and not the problem. Phillips heads strip because they’re designed to cam out and prevent snapping heads or overtorquing. JIS is same cross shape but doesnt cam out, which is good for avoiding stripping the heads but makes it easier to snap the head off of screws
Maybe in the US, but Pozidrive is very common here in Germany and other european countries in the form of “Spax” screws. They are the main screws we get for everything from wood working to wall mounts for pictures. They also don’t strip as easily as philips screws.
And trust me, I have seen plenty of philips screws beeing stripped ue to the use of pozi screw drivers while beeing perfectly okay when beeing removed with a philips screwdriver. Of course there are other reasons they strip as you mentioned, but here in Germany its a huge problem because Pozidrive is so common and people dont know the difference.
The reason for the stripping , that the shape of the tip is different.
Phillips heads are not designed to cam out. They were designed to not cam out. Common myth that keeps getting repeated, to explain their poor performance.
