Earlier quoted context omitted.
It’s $4 a month to sync Obsidian notes, for anyone wondering.
It's a good price but still feels wasteful if you also run/pay for nextcloud or similar.
And the notes are all just markdown files. If the obsidian software were to disappear you have all your notes. It's fine someone wanted to spend a load of time writing their own software but none of the reasons presented in this piece make sense.
