It has about the same problems with finding content that the www has, its just in the earlier stages

This has nothing to do with enshittification.

Yes, because it does not depend on a single entity, for-profit or not.

Neither does the normal web. It became this way. The ability to run decentralized is not what is preventing enshittification.

I would argue eg. a LoRa based Reticulum network is enshittification resistant, because of physical bandwidth and range limitations. It enforces decentralization and abuse/advertisement/... inherently doesn't scale, is not worth the effort. It favors authentic, low reach human2human information sharing.

The internet itself is not enshittified. Certain websites and services on it are. Heard of HN?

So, then why exactly do we need an alternative?

We need an alternative to the enshittified services, not to the Internet.
