Since you mentioned CKEditor 5, I'll be bold enough to go a bit into off-topic.

CKEditor 5 is an incredibly impressive endeavour, and I've been following it with great interest. However, one of the things that separates it from the competition is the GPL license, which makes it impossible to use the editor in a permissively-licensed (Apache2/MIT) open source project. Your founder has indicated a readiness[1] to grant a custom license to such projects.

So, I'm wondering whether that is still the policy, and how that's been working out in practice. Have any projects taken you up on the offer? Have there been any unforeseen problems? What are the legal limitations imposed (on distributors/forks of the project, for example)?
