I didn't say they were, I didn't say anything about MSN messenger. What I said is that Japanese emoji were not originally implemented with Unicode, therefore non-Unicode emoji are not improper or diluted emoji. Emoji does not imply Unicode, Unicode is just an implementation detail of modern emoji, it isn't and never was a defining attribute of emoji; for the first several years of emoji's existence in Japan, Unicode wasn't involved.
