Even though Lennart has been working hard to make people lives easier, it seems some people are working hard to make his life harder by making discouraging comments not just about his ideas but the great work he has been putting up.
First of all, if you don't know why a sound server is needed on a modern desktop environment, you need to research about it (asking Lennart or anyone who knows *politely* might be a good start). Making a big fuzz of your ignorance and being proud of it won't help anyone, especially yourself. If you had asked this question from Lennart and he didn't give you a nice satisfactory answer at that time, it must have been because he must be getting really tired of answering this same exact question so many times, over and over again. That doesn't mean a sound server is not needed. No need to rush to conclusions. Ask someone else and/or research more. God is in the details.
Secondly, if Lennart's software breaks some proprietry shit, it's really not his fault and the last thing we need is some random mono-hacker who doesn't even know why a sound server is needed, to blog about Lennart being the guilty party.
Thirdly, there is nothing wrong with GNOME having a hard dependency on PA and there is no need to uninstall GNOME. This is as silly as saying "so if you don't want to have gtk installed on your machine, just stop using GUI apps or change desktop".
No really WTF do you guys want from him?
