I think many people that come on websites arguing that they've never had it happen and they will just keep using them assume way too much like you stated. They figure that whoever had a misfire did something wrong to cause it when the inventor himself found out shortly after production started that his design itself increased the chances of something bad happening. It's almost impossible to make a foolproof firearm, but manufacturers try to make them as close to foolproof as they can because there are so many people that don't even know which end to point where! This particular problem probably wouldn't occur very often in a perfect scenario where the rifle is kept in immaculate condition inside to lessen what exacerbates the misfires. Unfortunately, the vast majority of owners have no idea how to disassemble these rifles or any other firearm they may have to keep them clean and greatly lessen problems that might crop up. Nope, they just run a brush or two down the barrel, give it a wipedown on the outer steel and call it good. That may work most of the time, especially with modern firearms and the way manufacturers can control their assembly. That was not the case on the old guns like RR pointed out and that increases chances of a misfire. Rather than mess with Remington my advice is to just bite the bullet and have an aftermarket trigger put in them that has less chances of malfunctioning.
