The expansion of the article is irrelevant the quality assessment. Please inform yourself about the differences Quality vs. Quantity. As far as I can see there are indeed sections being constantly removed, usually while citing Wikipedia guidelines that suit the situation. I also see sections being added against Wikipedia guidelines.
The suggestion to add useful information is welcome, but since I don't see myself as neutral regarding the subject at hand I'd rather stay away from it.
You have been pointed to problematic material in the article several times. It appears as if every time problematic material is pointed out, it is completely ignored.
Please note that maintenance tags, and this quality assessment, exist in an attempt to draw editors from the Wikipedia community who will help in improving the article. The whole point in these tags is to make the article better by advertising it within Wikipedia, to get experienced editors to take part in the struggle for a better article which conforms to Wikipedia guidelines and standards. I assume that you are in favor of making the article better, as it seems that the article and the subject are very dear to you, which is why I ask you not to remove maintenance and quality tags unless the community decides to remove them.
I believe there is general agreement that the article in its current state is of poor quality, although there are disagreements about how it would look better. Due to that and due to my assumption that you want the article to become better, and fit Wikipedia guidelines which is a necessity for featured articles, I ask you to replace the quality rating and replace whatever maintenance tags you removed against mutual editors' agreement. 109.186.10.101
