You used two different symbols for OR. OK. Interestingly, it's tautology either way! And it's far from clear how this tautology somehow "blows up" material implication.

Huh??? It is statement that is true in the present in every case.

Not sure I follow you, but A implies B is NOT the same as A causes B.
Example: Scientists have now proven conclusively that smoking causes cancer. But smoking does NOT imply cancer. Many smokers never get cancer. I hope that much is obvious to you, Ross.
not just a misnomer

I have repeatedly posted here the rationale behind each line of the truth table for material implicating using what amounts to first principles for NOT, AND and IMPLIES operators. See: https://dcproof.wordpress.com/2017/12/28/if-pigs-could-fly/
