Obviously we all look into drugs we might be taking so I get the reason going there, but people tend to be more motivated to mention concerns and
complaints and commiseration and let positive experiences ride without mention. For example, I use an IUCD for birth control. Could easily google 100 outlier horror stories, but that doesn't reflect my over ten years of blissful usage, because I've never been bothered to mention it!
It's just a little quirk of human nature.
