Because the value of a second brain is proportional to how little effort each save costs, and Mymind spent years shaving that cost down to one click from any device. A self-hosted clone tags almost as well now that models are cheap, but it lives on your laptop behind a localhost URL, which means the thing you saw on your phone at 11pm never makes it in. People also pay for the privacy stance and the promise of no social features, no sharing, no feed, which is easy to replicate technically and hard to replicate as a trust relationship.
