"That’s not real encryption! And who the heck encrypts the weather anyways? It didn’t make sense. Why would a company bother to invent a terribly bad encryption technique in order to obscure data that isn’t private? The next oddity was that the last byte is described in the PDF as an “exotic” checksum. Huh? What company would bother to invent their own checksum technique? Are standard checksums not good enough?" I have seen such behaviours, where two companies' products has to be able interoperable, they would introduce odities in the communications protocol to confuse the opposition and claim the oppositions product is crap...
