From the article:
"Beehaw is relatively new and relatively small at the moment, but it’s one of the closest approximations of what Reddit is that you’re going to find, and well worth investigating as a Reddit replacement. The interface even looks a lot like Reddit, albeit without a lot of the on-screen features and furniture that build up over almost two decades of operation.
Have a read of the Beehaw mission statement and you’ll see the platform is committed to avoiding the “hate speech” and “disinformation” that’s prevalent elsewhere. The communities available right now cover everything from neurodivergence and people of color to literature and gardening, so you’re sure to find something of interest here."
I wonder if it might be due to the work needed to figure out which Lemmy instances are/aren’t moderated and the allowed content. Beehaw is very upfront about wanting to promote an inclusive online environment and what kind of content they’re willing to host, making it a safe choice.
That said, generally mentioning Lemmy/Kbin doesn’t seem that risky of a bet if you used Beehaw as an example instance.
It’s a listicle so you can bet that it was written solely as a low effort way to pump out an article.
