Why is .lzh format still popular with japs?

The rest of the world uses .zip and .rar and these retards still seem to use .lzh a lot.

Oh, and all of you who are dependent on the Windows shell to open programs and run your computer life are DUMBASSES.  So you got to click *twice* to open a file.  God, stop it already.
