Violation of several licensing agreements
I was wondering when you plan to make the source available for your zextra's product you are distributing with ZCS-NETWORK.
There are several packages in your code which require source distribution, and you are failing to do that.
oio api - Lesser GPL
AlbiteZIP - Derived from GPLv3
xmlpull - Lesser GPL
Your contribution to Open Source helps everyone as well as helping your customers solve their own issues.
Decisions to abide by the licensing are not optional. So I hope you will take this heads up as incentive to release your source or abide by the license.
