From context it just sounds like they were saying that a post with that link followed immediately after this one in their lemmy feed. Coming off unnecessarily aggressive.

You should be able to figure out what feed I'm referring to in context. I'm on lemmy. It's obviously the lemmy feed.

And what's described is a major news event that there are dozens of high quality sources for. I just threw something up to answer my own question about what even this post was referring to.

Despite pontificating about sources, you're demonstrating extremely poor critical thinking and source consideration. The first step of research is figuring out just what level of scrutiny is required. This was a throwaway line to quickly answer a throwaway question, and you're going down some weird rabbit hole demanding other sources when quick googling could find any number of sources.

Try to use better information practices. It's poor form to be demanding additional sources when casual sources suffice for a casual problem. If you want something deeper, you are more than capable of finding it.
