@fourstepper @logseq @obsidian That would be a good question for big open source projects who may have lawyers to advise them. For Joplin, this was mostly my decision and done "just in case". AGPL is suitable but not perfect - if a better license comes up later on, then we can switch to it. With a CLA we can do this, without it we're stuck with the same license pretty much permanently.

@fourstepper @logseq @obsidian Hello, any open source project of a reasonable size is going to require a CLA. Firefox, Apache, Signal and many others do. They exist because if the license ever needs to be changed it would be impracticable to get the authorisation of all previous contributors. That being said, just because there's no CLA doesn't mean the license will never change. An MIT project for example can have its license changed with or without the contributors agreement.
