Because the publishers no more allow scanlations.
Official say at onemanga.com.
The webpage One Manga has many manga stories. These include Naruto, Bleach, Claymore, One Piece and Vampire Knight. The webpage also features a forum.
mangafox have more manga but personally I like onemanga better, I think it is more organized.
You can find it in Mangafox or Onemanga. These are free manga reading sites.
1-24 are all on Onemanga.
death note the manga can be read on mangafox, mangareader, onemanga and other manga scanalation sites
Naruto is manga.

There's basic Shonen(boy manga like Naruto and One Piece, Inuyasha etc.) Shojo:(girl manga like Hana Kimi, OHSHC, Kaze Hikaru etc.) Ecchi:(mature female manga) Seinen:(mature male manga) Joise:(mature female manga) some good free online sites that you don't have to download are Mangahut Onemanga Mangafox
Chapter 489 of Naruto should be released on OneManga on either Thursday, April 1 or Friday, April 2. Thursday and Friday are the usual update days, but they have been known to be up as early as Wednesday or as late as Saturday.
You could go on Manga Fox. and Manga Fox has a lot more manga than one manga. Also try out Shugo Chara!
When a manga is licensed it means that it's no longer available in a raw form; meaning that as soon as the new Japanese/Korean chapter is available, it's illegal to translate it and post it online. You'll just have to buy the English manga, where as a big batch of different titles such as Naruto and Fullmetal Alchemist have been licensed.
Manga is the original Naruto/Naruto Shippuden source in which the anime comes from.
