I don't think the article claims A). The claim is that YC prefers companies that match a certain pattern and if yours does not then chances are not great. It mentions that other accelerators could be a fit though. It does not claim to have figured out how to not get rejected. What would be valuable though is if they posted the feedback and rejection reason that they got from YC.
