As a mechanical engineer who spent 10 years designing flight controls for Boeing, I have to weigh in on this. Accidents happen. Planes crash, Firestone tires come apart, SUV's roll over, hot coffee gets spilled, etc, etc, etc. Accidents happen. Manufacturers of a product try their best to produce a product that works and is safe to use. If accidents occur, then analysis and redesign occur. Typically, engineers do their best to think thru all possible failure modes, and work to eliminate them (I am referring here, of course, to highly engineered products, which a firearm certainly is). Sometimes they miss them, or a product is used in way that no one thought of, and then it fails. An example of this would be using a cinder block as a jack stand for a car - the block (material) is not designed to support the compressive loads of an automobile. When it fails, somebody gets crushed. Sometimes, though, SH## happens, and a design just has problems. In this case, remedies need to happen.
A responsible manufacturer should be willing and able to step up and address failures, particularly when a safety system fails. We can argue all day long and thrash the keyboards until they scream about gun handling safety, not pointing the muzzle at anything you don't want to shoot, blah, blah, blah, and I will agree with you. Proper gun handling is key, but the reality is, is that one has a reasonable expectation that a rifle will not discharge when the safety is released. I would argue that it would be better to have NO safety on the rifle, rather then one that fails in operation. Mechanical safeties are no replacement for safe gun handling, I think we would all agree. But the presence of one implies that it will work as intended. The Remington design seems to have more failures (20,000 or more, I read somewhere, Remington estimated). I wonder if 20000 Winchester or Mauser 98 or Weatherby safeties have failed, resulting in a discharge when released.
I would also guess that like Tripod posted, everyone on here has had their muzzle point at something they didn't want to shoot. It's just a fact of life. Hell, holstering a pistol points the muzzle at a lot of things I don't want shot.
