Going through the GitHub page for the bot, it seems that this is intended behavior by the dev. In their own words:

I think it still serves its purpose of people not having to leave the community to see what the article is about.

I agree with this, personally, as I don’t like having to follow links to read articles. It’s nice having a comment with a TL;DR, or for very short articles having the whole article in the comments. Plus, it’s not like one (relatively short) comment really adds bloat to the comments section, it’s something that can be easily scrolled past.
