This rant makes little sense to me. Linking and COM are mostly orthogonal issues for once, and ABI compatibility in windows is not directly tight to COM. I think the lack of ABI compatibility in linux has more to do with incentive and economics: innovating while keeping ABI is very difficult and ressource-consuming. I don't understand why Miguel would cite Apple, as they are pretty lousy in that department, whereas MS famously spend tons of resources on that issue.
