With the experience I have had with Clip Studio on ipad, I am not sure porting Krita to iPad would be a great idea. At first I loved the idea of a full desktop app on the iPad, but as one usually uses it without the keyboard it becomes a lot less efficient to use than it would be on a real desktop. The UI is not optimized for touch, so the interface becomes quite cramped which is not nice to use. The interface can be changed and made to fit a workflow, but it is not a very good fit (at least not for me).
Another issue will be performance, which will never be as well optimized than the apps developed exclusively for the iPad. Using Clip Studio with brushes over 500 px is already quite laggy on a good Mac, and even worse on my iPad.
I would rather suggest the limited resources be focused on the current platforms, as there is too much choice on the platform already in a lower price bracket that I feel the market is saturated.
I have used it a few times with the Sidecar function, which is free. Though this is not ideal (touch is not supported, pressure sensitivity is way too stiff) it can be used to a certain degree and is free.
Chiming in to say I would also love Krita on iPad, and would be happy to pay for it. I’ve always preferred its brush engine over procreate, and it would seriously make my workflow easier.
I do agree with your last suggestion. It would be nice to have Krita on iPad since a large number of artists are on there, but it might be hard to compete at the estimated price point as well as limited developers.
Krita and Blender use two different versions of the GPL. Blender decided not to move to the GPLv3 when it was published, so they’re still on v2 similar to the linux kernel. Krita is GPLv3 only. Blender could have done two things: Distribute a non GPL build (which they have the right to as copyright holders) or apple interpreted the GPLv2 just enough to make it legal to distribute on the app store.
As pointed out above, the GPLv3 is much stricter than v2, so it’s even harder to get GPLv3 apps on the app store. Note that apple used to and still does, distribute GPLv2 applications like the bash shell, so they’re not entirely against the GPL. They just strongly prefer version 2.
All the components that together make Blender are compatible under the newer GNU GPL Version 3 or later. That is also the license to use for any distribution of Blender binaries.
