I used to (and still am) one of the highest ranked editors you can be without becoming an administrator. Wikipedia has its problems, and I spent years fighting them- but I slowly realized there is no better way to do it.
Wikipedia is not an arbitrator of truth: everything needs a reliable, secondary source[0]. This means the content has to be notable enough that a reputable source wrote about it, and you cannot reference things like git commits or research papers (since they don't provide context and most people can't understand them).
If a Wikipedia article does use one of those sources, delete the paragraph. If you get into an Edit war, you'll win.
