Just write a description in the main post and put the link in the reply. This just stops lazy linking.
I agree with Elon’s sentiment in this (though sticking a link in a reply is kind’ve inelegant — imo, Lemmy would be better for this, as it has a separate title and body). This is something that bothers me on Lemmy; I’m not super fond of the practice of simply copy-pasting articles from news sites into posts; it feels very lazy and spammy. Lemmy is under no obligation to repeat the clickbait and misinformation that a news site may be compelled to use. When an article is shared, I think that it should, in general, be used as a source to back up a claim rather than the entire post itself. Posts should be human oriented rather than just an outlet for news spam.
