I'll vote to leave it up. Even though the thread is more concise than some other fuse-related threads that have appeared in the past (for example the "Fuses that Matter" thread that began in 2012 went on for 17 pages), arguments and rebuttals have been stated pretty thoroughly on both sides of the directionality issue. Taking it down would just increase the likelihood of a similar thread appearing in the future, with the usual protagonists then having to re-compose the same arguments.
