Because they go too far, and exclude fingertips, when they ought to be teaching how to (gently!) use vacuum and van der Waals forces (stickiness) to remove the wax, or at least move it away from the sensitive workings. If you don't clean, and your canal partially collapses or is narrow for whatever reason, then it can seal, cut off oxygen and cause permanent nerve damage that can lead to permanent discomfort and pain. There are risks on both sides, not just on one side. Our bodies want it out for a reason. Just not with a nail or other tool. Darwin and Evolution can't be swept aside; our wish to remove earwax is not a silly artifact.
