The article is pushing the limits between fact and opinion - it isn't a question of the truth. I don't think the last two paragraphs are really necessary - perhaps a reference to some controversy but there isn't any need to have a a dedicated paragraph refuting all the claims of plagiarism on this type of pedia. The actual Serebii.net website should be responsible for maintaining its own integrity not other party's sites such as Bulbapedia which being within the public domain could spark more controversy.
