Points that are conveniently being omitted by folks who don't want the hear the INT side of the argument.

The batter moved the bat. Don't care if it is still on her shoulder. If a pitched ball hits the bat on the batter's shoulder and roles to the pitcher, are you going to ignore it? If the batter moved the bat to take a practice swing, would it be different? If so, how? The batter would still be interfering with the play.

The batter moved in a manner NOT associated with their natural stance, swing or reaction. That is 'actively hindering'.

The fact that it hit the catcher is irrelevant as to whether the ball is still live and the defense have the opportunity to make a play and/or get an out on an active runner.

It was an accident. So what? It's an accident when a batter ducks a high pitch that hits the bat, but the results are the same as if the contact was intentional. It's an accident when the pitcher drops the ball during delivery, but it doesn't mean we ignore it. It's an accident if F3 fakes a throw to 3B and the ball slips and goes out of play. Do we ignore that?

Instead of trying to justify ignoring a rule, try thinking about it from the defense's side. After all, there are two teams out there. Not all things are fair. The batter made a mistake. $hit happens.
