The above rule has been added to the instance and will be enforced instance wide. This rule is very common within most existing communities where news articles are shared and avoids sensationalizing the story or attempts at steering discussion by the user posting the article.
This seems like exactly the sort of rule that should be applied at the community level. Instance level rules should be kept as minimal as possible.
