They didn't blow it out of all proportion, it's a valid and nasty issue that destroys people's gameplay experience but like any product a vast majority of customers don't need to have the problem to get it fixed. It probably don't affect so many people because they don't play it for long enough as well. Bethesda's Q&A missed a lot of bugs that should have never made it into the release or patches.
QA for any game will miss bugs (or leave some in to be fixed via patches) before release, especially in an open world. Think of how much testing the game already had, and then think of how large the world of Skyrim is, all the possible character interactions, and all the possible bugs that could be present in the world. Then take into account the fact that most QA testing results in new bugs after old ones are addressed, resulting in more QA testing, resulting in more fixes, and so on and so forth.
Also, I love that you can't actually appeal to the fact that the bug was experienced by a significant portion of the playerbase, so you have to resort to saying that people must not have experienced it because they weren't playing long enough. Classic.
