All manufacturers mess up. I've been lucky and never had an issue with any keycap, from any manufacturer, but I see this kind of thing with everyone. GMK just have a more critical spotlight on them, and when things like this happen, because they are expensive, and people have waited two years, they make more noise about it, and you are more likely to see it. I'm not excusing them or anything... just saying that there's no more reason to not buy GMK than any other manufacturer's group buy sets, apart from wait times of course, but you have all that to worry about with others as well. GMK aren't unique in the long wait department.
