So. its imperfectly translated, not to be taken seriously, and isn't technically canon lore... So why is it being discusses as if it was lore?
Other people have been citing it as a source of information and I want some other sources besides that. I didn't neccesarily want to discuss that text specifically, but so far its the only thing I could find with any info. I never claimed it was lore either, but that it is based on it.
And, you're wrong, he also wrote some things for Oblivion including part of the main quest. If you aren't interested in his work then fine but don't try to diminish his credits.
people act like he was the soul inventor of elder scrolls
I think a lot of people respect him and enjoy his work because it at least shows a comprehension of Elder Scrolls lore, while some of the newer canon (mainly parts of skyrim's main plot) appear to be full-blown retcon.
