If the source didn't know about the hotfix, what else could the source not really know about? Also, if the report was released hours before the hotfix was released (which means that the hotfix was already in the works at the time the report was just being released) it's kind of strange not to know about it if you really have actual insider information.
All I'm saying is that insider or not, it doesn't really mean anyone actually really knows anything. And even if some or most things fit with what some insider has shared, it might in the end be closer to some guessing than anything else. Insider information (as in if it's known to actually be insider information) isn't to be completely discounted, but at the same time can't fully be trusted either since even if it's 100% true at the time of "leak" things change all the time.
