I actually sent a message to them recently, and now I got today a response.
Here is the copy of the mail I received:

Hi
B1 Pack Project is open source, you can use the code to work with b1 format
and .b1 files.
B1 Free Archiver as desktop and android applications are just free, but not
open source.
We are going to keep it free, but for now we have no plans to public the code
of the apps.
But if you need any help with b1 format and the libraries I'll be happy to
help you.
Thanks,
Adam
