So your view is that you have not encountered any bugs and are happy - thus everyone else is only imagining bugs and should be happy ? El Capitan is the worst "upgrade" OS I have experienced. Apple trackpad will not function, web surfing is slooooow, some applications are also slow to load. Your experience is different - good for you - don't discount that others are having a different experience.
I believe he was saying that you may not experience the issues reported by someone else on the forum. Case in point: I have been using El Capitan betas from day one and have not experienced any of the issues you identified. In other words, your issues are real; but not everyone will experience them. So, the best you can expect from reading the forums is to be informed of others experience. This does not mean you will experience those issues. That was the poster's point.
Also, Tim Cook is nothing like Steve Balmer. Balmer drove a successful company to the brink of irrelevance. In contrast, Tim Cook built the global logistics machine that made Apple relevant. Steve Jobs knew this -- which is why he named Tim Cook his successor. Apple would not be the Apple of today without Tim Cook. Please respect the man for his substantial accomplishments and contributions.
