With that I can mostly agree (but the comment implied otherwise). But - and this is sometimes a huge but - open source software (OSS) is more and more dependant on other OSS, making it sometimes next to impossible to port it to other platforms. Try building VLC from scratch and you'll see what I mean (you can use Linux). Furthermore, API changes are quite common for OSS even in minor version updates and that creates an additional mess (dependency hell), as was clearly demonstrated in my example above. It's not all black and white.
