This actually respects the license. The person who provided you the binary (the phone vendor, not KaiOS) must provide you the source that corresponds to your program (not the git history). KaiOS must provide the source to the phone vendor on request off course.

That being said, this is the minimalist interpretation of the license, and not what is commonly understood as open source (where the repo is available somewhere, at the very least).

I wonder how difficult it is to get the source from the manufacturers. If it was trivial you'd think they'd avoid playing these games and just dump it as a tarball at the very least.

You just have to fill out the form in the disused lavatory next to the door marked "Beware of the leopard".

So the repo is available! Thanks, I took @omnifischer at face value.

Looking at the commit history, they keep on referencing bugs in a private tracker though (I know I'm moving the goal posts :-).
