Let's switch other source files to MIT license since we're absolutely
NOT working on secret rocket science, so licenses should not be
a bottleneck to innovation in the Cloud Native and AI era.

@@ -3,13 +3,13 @@ erofs-utils uses two different license patterns:
- most liberofs files in `lib` and `include` directories
use GPL-2.0+ OR MIT dual license;
- - all other files use GPL-2.0+ license, unless
- explicitly stated otherwise.
+ - all other files use MIT license, unless explicitly stated
+ otherwise.
Relevant licenses can be found in the LICENSES directory.
-This model is selected to emphasize that
-files in `lib` and `include` directories are designed to be included in
-3rd-party applications, while all other files are intended to be used
-"as is", as part of their intended scenarios, with no intention to
-support 3rd-party integration use cases.
+This model is selected to emphasize that erofs-utils can be integrated
+into various ecosystems as much as possible.

+However, liberofs should be GPL-2.0+ OR MIT dual license since some
+parts can be shared with the Linux kernel.
