I used to be very against closed source products but changed my mind recently. One of the founders of Obsidian makes some great points here: https://forum.obsidian.md/t/open-sourcing-of-obsidian/1515/1...
> The cost to benefit ratio is very low for our small team of 2, and our plate is already full.
Wow, I didn't know the team was so small - go them!
This is a great rebuttal.
99.9% of the internet is closed source and we don't ask for it to be opened. From our ISPs, to Google, to the hyperscalers.
If anything, I think we should be asking those things to be open. If we're only asking the little guys, the big guys with trillion dollar market caps skate by. This is exactly how they want it. Fewer gradients for small players to grow.
> From what I see of the pricing options in your business model, having your code released under a FOSS licence would make no difference to how you make money.
Except that making their client FOSS would help a lot to replicate the APIs and create a FOSS server, which would definitely make a difference on how they make money.
