He does note he did a fresh oil change with 5w-30 the day prior to this. It's really unknown until an engine teardown is done to confirm if there's a crap ton of silicone clogging the pickup, but I wouldn't completely rule out the possibility the oil change was underfilled.
I'm not attacking the owner, but I've seen a lot of people think they're all good to go, like putting on a new filter, filling up to the "full" dot, and calling it day. As much as I autocross, I prime the system, start the car, drive it around, and come back to top up whatever might be needed. A lot of times people are running their cars a quarter of a quart under that full mark, or more. Which might be ok for the street, but then toss some good G's on the track at it and you could put yourself at risk.
But who knows. All just speculation. Can't simply just blame it on RTV and Toyota/Subaru and call it a day. There are many pickups out there with a good bit in/on them and limited failures.

Agreed. Drive article mentioned that the dealer found a large hole in the top of the engine block. That is not the same type of failure we have seen with the RTV issue. And would also like to note that just because the engine failed at the track, doesn't mean the cause of the failure was expereinced at the track as well. Things like over-revs that cause engine failures could've happened several hundred (or thousand) miles back...and the part just happened to finally let go at the track.
