And if someone produced work for 15 years, and edited 10000 articles... very hard to argue it is not permanent worker!
Wikipedia can easily work as "marketplace of ideas", linking original authors. That is not possible if you have editorial policy, political opinions and work like a corporation or a news paper.
If for example you edit in racist views and leave the attribution of the original author because it’s just a one word change from “the holocaust” to “the alleged holocaust”, then yes you are open to a lawsuit for any harm that results from that malicious edit.
This is especially true with my example as that view would run afoul of criminal statue in many counties.

Edit: I also wonder how or if this works in reverse, if someone wrote a fantastic article on numerology or whatever with a screed halfway through, would removing it from the article violate their moral rights? I think any framework where the answer is no is also probably going to be unworkable.
This is generally not true, but more importantly Wikipedia does not ask people to waive their copyright rights, only license it under a creative commons license. Its no different than how open source software works.
