Not to white-knight microsoft here, but I think the problem they run into with every product is that because of their ubiquity, they rapidly reach saturation with most every specialized product they sell. You cannot grow a business if your market is saturated, even if you're the only one selling. So they have to find a way to expand their market. With specialized tools, that's done by generalizing, right? And anyone who has ever driven a screw with a swiss-army knife can tell you, generalized tools never work as well as dedicated tools. Thus, Word ultimately sucks. Windows ultimately sucks. Github ultimately sucks. They are all of them trying to be everything for everyone, because the alternative is just mumbling along, being really good at being tools, but being really bad at conveying profit to their creators.
