Next up is #Obsidian, a tool I'm hesitant to consider because of the developers' view on open source. Hence, the source is not available except the obfuscated JavaScript that's ran by Electron.
Despite that, Obsidian itself only does a version check (which can be disabled) and starts in "restricted mode" by default, which disallows third-party plugins (but does still embed external content when asked to.)
There's some phoning home by Chrome but far less than with Logseq.
Color me surprised.
