This is an odd bit of gatekeeping and I really don’t understand your position here. Calling this egregious seems odder still. It suggests that companies that choose to publish how they do things have some obligation to do so under a specific framework or shouldn’t do so unless they’re willing to get public buyin.

Many of the best projects that become defacto standards start as a solution to a very specific and real problem that had no public input.

If JSON canvas isn’t a good solution for broad adoption/interoperability, it won’t become one. The world is not harmed by its release, and at worst, it’s now far easier for people building software to understand and make tools that can interact with Obsidian. At best, it becomes a solid foundation and option for tools going forward.

Obsidian didn’t have to do anything here. I’m glad they did.
