Rule 1 Definitions: Foul Ball
D. While over foul territory, an offensive player interferes with a defensive player attempting to field a batted ball.

This comes back to what "play" would have been made if F3 got the ball at that point. None. So it is not INT.

7.6.K only allows INT on a foul fly ball.
Contradicted/muddied by 8.2.F.1: When the batter-runner interferes with a fielder attempting to field a batted ball.

So, Foul Ball, with an ejected participant.

The only pdf rulebook I have here is 2005. It's definition of rule 1 reads while over foul territory, a RUNNER interferes with. Assuming you're quoting a more current version, this solves some of the problem in that thread. 8-2-F is still a problem. Does 8-7-J still say fair batted ball?
My biggest problem remains that if you don't just call this a foul ball, it's incredibly weird that you do still call it a foul ball when the runner on third does exactly the same thing. And I can't believe anyone is seriously advocating for actually calling it a fair ball on the field.
