This is nice to see..
A student can't afford to pay the $8 per month for #Obsidian sync, so builds a #FOSS alternative. Then posts to HN and says "I probably violate ToS, so will take down the repo if asked".
Then the Obsidian CEO replies. Explains they aren't VC-funded and the $8 bucks subscription keeps the light on. Applauds the work of the student, points to other open ways that content sync can be handled and gives advice "if you rename, there's no ToS problem". 👍
