[zeromq-dev] [ANN] zmq.rs - native stack of ØMQ in Rust

[Pieter Hintjens]

Fantix,

I'd recommend keeping the MPLv2 license, since otherwise you cannot
merge pull requests without further clearance.

The problem is that a fork of an MIT-licensed repository will not
necessarily be MIT licensed. It's trivial to add code and relicense
the lot under a different license. Then, when you get a pull request
you have to explicitly check or ask that the patch be licensed
properly. It's significant work and if you don't do it, your entire
project may end up with an inconsistent, even unusable license.

Sticking to MPLv2 (or LGPL as for libzmq) avoids that work and
eliminates the risk. By definition a pull request is safe to merge.

This aspect is so important that C4 makes it mandatory. If you use an
MIT license, you cannot be compliant with C4.

There is also the argument that a share-alike license increases the
incentive to send patches back. I've made MIT licensed libraries that
were widely used and yet got very few patches.
