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.

It's not because the format itself was constructed by a "fellow" Jap is it?

Oh, by the way, since I just know you're going to be stupid: when I say an uncompressed zip, I mean a zip that used zero compression, not a zip that has yet to be zipped. Zipping a zip that already used compression won't help, just so we're clear, mmkay?

PS. You're an idiot.
