I don't know. I just came across it yesterday, and I thought it'd be something interesting to share.
It was explained in the post's body actually:
Curiously, it does not list Lemmy under the list of Reddit alternatives.
Most of the people here know about the Lemmy devs political stances.
Seeing as I've only started using Lemmy less than a month ago, I've only just very recently started realizing that.
I'm not new to the Fediverse, so yes, I'm aware of that, and also of the drama that comes with defederation (lmao)
Or in other words, they're much less likely to just shut down without notice.
