Not fair at all. As I said, I genuinely didn't know the rule.
I asked if I should be annoyed and you posted the official link to the relevant law. I then actually read it. I wanted to know if it should have been handball.
How is using ALL the examples given in the official rulebook to interpret it "bending" it? lol It says quite clearly a major advantage needs to be gained and I've interpreted it using the information that they (you) provided.
You're saying that any change at all to the trajectory of the ball (so any contact at all) would count as a defensive advantage. Fine. I'm sure you're not making this up and it exists somewhere, so please post it as I can't find anything currently. Certainly not in what you've posted at least. I've no problem then changing my view completely.
OK, I'll take you on face value.
The advantage is having the illegal contact of the ball where it wouldn't otherwise have happened. That's the defensive advantage. It doesn't matter where the ball then goes, it's still stopping the ball from going the way intended.
The rule says and gives a major advantage from an attacking perspective as an 'explanation', not as part of the rule. It's actually explaining the previous set of rules - namely these - that deal with
offensive football.
The only reason the word 'usually' is in the next set is because it's allowing for situation where the attacking/defending player has been ragdolled and has no control of their body. It says exactly that in the explanation.
Note the bullet points - it's adding literally
point by point further clarity, which is why the first few refer to an offensive version of a handball.
Your mistake is the interpretation of the word "usually". It's only there for 'natural' reasons for the arm to be elevated above the head, which is why it can't be definitive - nothing more.
