Why did flipnote hatena discontinue on thile internet and NINTENDO DSi's?

thile　は　文意から、whole　の書き間違いですか？
the reason they quited flipnote on old DS is guessed of financial difficulties, old flipnote was completely free (from payment) service.

today they uncovered that old DS's wi-fi network will also discontinue.
