To put it more diplomatically, some articles on IL are written by Bethesda, while the majority are written by fans. As such most of the articles there are fan-fiction. Well written and well researched though some may be, but still fan-fiction.

However, Bethesda has used articles from there in their games before (i.e, Heimskr's dialogue from Skyrim was from a Kirkbride article), so I'd rather view the IL and its writings as a limbo. Neither canon nor non-canon (unless it directly contradicts the games, for example if an IL article said Balgruuf was a 10-foot tall Argonian, that would be non-canon).
