You are of course right, refering to Wikipedia on a Wikinews "Wiki does not exist" page is not very useful. That should be changed too!
Your second point: of course there is no "wrong" as in "1 + 1 = 3 is wrong". Low Saxon has no commonly accepted orthography. But of course spelling for English, Dutch or German has no "wrong" and "right" too. Only "following the commonly accepted convention" and "not following the commonly accepted convention". Platdüütsch is not wrong, but it does not follow the most widely accepted spelling convention. Google for it: 12,1 Milllion for Plattdüütsch to 825 for Platdüütsch. I thinks that's obvious.
I guess, you were suspecting, there is a controversy behind it. No, really, it's not controversal, it's really nothing than a spelling slip.
There are no right and wrong spellings for English, certainly, but I believe German does have official spellings. I've no idea about Dutch. Not that that changes anything - a spelling mistake is a spelling mistake.
