This is one of my favorite projects and a cornerstone of my structure. I would love to be able to help develop it and have no problem supporting it. I do believe open-sourcing it would accelerate its development and maybe create some alternatives based on it (not great for business). The forks question could be addressed with the license and I believe more than enough people will be using the sync and publish functions which would be invaluable for some. An open-source business model that comes to mind is red hat.
I’ve been looking for a project like this for years now and I’m so happy to have finally found one, being here since the early days. The only obstacle in sight is it not being open source. I’m incredibly thankful for Obsidian and development has been unbelievably rapid. I’m here to offer my support for open-sourcing it and making it the go-to knowledge management system of the future.
