content: Not true. There is no one filesystem for every task. Anyone telling you otherwise is an idiot. Some filesystems are still around for legacy reasons. Some target specific environments or physical media limitations. You also completely ignore the fact THE primary reason Linux has the most advanced filesystems is specifically because of the gpl. The one exception being zfs, which is a filesystem of corporate creation. What people fail to understand about open source is that only idiots believe it's pro communism. The entire purpose is to empower developers. Developers and companies have poorly picked up this part of the equation. It is actually very capitalistic. You also appear to have no clue what software development was like pre-90s.
