Because anyone can edit the articles/content on their pedia, even if you do some projects based on it then they might not get approved anywhere.
It is called
Community (
https://en.wikipedia.org/wiki/Community).
Wikipedia is a community for Knowledge.
You need to trust people to grow, that's how it works.
Wikipedia is not crap, is you that are grumpy.
Best regards.
Yes but what community says is not a Fact ? I have seen many articles with all that manipulation regardless of right or wrong.
It is not a source that could be trusted anymore.
