ther's no prevailing, that's the point. i am very critical of linux development that is not done in true open source attitude, the LSB however seems to be true open source style, ie a distro can be as eclectic and unusual as it likes so long as it conforms to certain expected standards, like how one app might be in a directory other than where you expect it to be, some flags may be different for an app, depending on the version et c. They want to standardise all that so you only need to know one set of commands, and you use less time looking up the man pages, and typing whereis, which and whence and so on every time you use a new machine.
As to linux prevailing, who cares? if it's a better OS, more people will use it, linux isn't the OS anyway, it's the kernel, GNU is largely the OS, sadly that OS seems to need to be partly nonGNU closed source stuff though, due to the proliferation of closed source, non-free technologies, libraries and file types.
