It's not a "no on giving back". You only have to make available the source for products you ship, and KaiOS itself is not the one shipping the devices, so it's up to the OEMs to provide the source they use on their phones (they do their own customizations).
That being said, I'm trying to get us to open source the "base" version which is provided to OEMs.
