Even though ASA removed the word "intentionally" from many areas of interference, oddly enough they kept it in their interpretation. If the runner knows they are going to interfere, they must avoid doing so. However, they still are not required to have eyes in the back of their heads. Always consider who caused the problem. The defense cannot and shall not be rewarded with an interference call and and out if they create the problem. Common sense still applies.
I dug back through my old ASA rule books, to back before "intent" was removed from most of the interference rules. Even back then, the rule reads the same as it does today. "Intent" wasn't in the rule then and it's not in the rule now. So, this wasn't one of the rules affected when "intent" was removed from many of the interference rules.
When it comes to interfering with an uncaught third strike, most softball rule sets are downright Draconian. The batter-runner has a responsibility to not interfere, intentionally or not, and whether the defense misplayed the ball or not. In contrast, most baseball rule sets allow the umpire to determine intent and the batter-runner gets a break.
Personal opinion here: I prefer the baseball way of calling this. The old argument is that it's impossible for an umpire to be a mind reader and know for sure what a player's intent might be. Yet there are plenty other rules that require us to judge intent and we somehow muddle through all those.
It is interesting that in this situation, people want to accuse the defense of creating the situation by not controlling the ball. However, no one wants to blame the batter for actually allowing the pitch to become the 3rd strike.
I prefer the intent to be part of the rule, but that mind-reading argument is a sad excuse for weak umpiring. Any decent umpire who knows the game can identify a player's action as intentional, or not.

As for the timer issue, I have had time expire during a last at bat. People would think it's impossible but with thousands of timed games, it's bound to happen. I've even had a fly ball with two outs and the clock expire with the ball in the air. Not folklore either. If you do enough games, it's going to occur.
I don't put the timer on the fence though. I've seen them hit with foul balls and break. It also encourages coaches and other to leave the dugout, which is the opposite of what they ought to be doing. I've even seen a spectator stop the timer that was on the backstop. Needless to say he missed the rest of the tournament.
