i think that dead internet is another form of enshitification that’s more common on platforms that are backed by significant financing. eg reddit, facebook, bluesky, etc.
anecdotally: your experience gets richer on social media if you avoid platforms that describe itself as “general interest” or with investors behind it since both have an interest in trying to attract as many people as possible rather than letting people’s interest organically lead them to your platform; lemmy was a great example of this before the reddit enshitification.
very true and add something like this to moderation actions as well.
