Why people look for a Obsidian alternative

Obsidian is free, but the parts that make it a team tool are not: Sync and Publish are paid add-ons, and commercial use needs a licence. The bigger issue is that the core app is closed source, so the plugin ecosystem is the only extension path and it is maintained by third parties. Notes are plain markdown, which limits lock-in, but the mobile apps and sync layer are not.
