I don't think you mean to sound condescending, but it comes across that way.
Most of the people on this forum who have reported this issue are competent photographers who know how to use their cameras and aren't "fumbling multiple buttons" repeatedly and consistently, which is what would be required in order to have multiple freezes. In fact, I would wager a guess that for most of the photographers who have experienced this issue, at first they probably assumed it was "user error." I know I did.
Experienced photographers know full well that in the heat of the moment mistakes happen and chalk up an incident to a mistake -- the first time or two. But, when it happens multiple times under different circumstances and you see others reporting the same issue, you know that it isn't an issue with your own technique.
I suspect that confirmation bias also makes many photographers less likely to report or identify the problem. When you've spent thousands of dollars on cameras and lenses from your preferred brand, the natural inclination of most people is to want to be satisfied with their purchase. It's no fun realizing that the equipment is not functioning properly after you've invested in it.
This is a real issue. "Rare" or "Widespread" may be a question of perspective. But, just judging by the number of competent photographers on this forum and elsewhere that have had this problem, it certainly feels widespread.
