Hot take, but that guideline is just bad. It removes necessary context and may even obscure relevant developments in a public dialogue. Original posts make sense only if the repost is not adding to the dialogue or otherwise making interesting contributions.

(If you disagree, this may the one time I will actively ask you to flag this post, so a mod can respond to this point)

Perhaps some sort of convention, like /r/science could be followed (like having OP post a link to the article or reference as a top comment).

This. Whenever I post a comic and something funny comic on Twitter/FB (i put credit: URL their home page or IG), but on Reddit, there is no such thing. Most Reddit admins also ban direct linking to sources due to spam or remote server overloading. So instead, you need to use Imgur or Reddit's hosting. So I write a comment saying credit which often gets enough upvotes to push at the top of the thread. I think those content creators deserve traffic and recognition too. It is good karma for everyone.
