it is not clear to me how a license that explicitly says it is okay not to contribute back would increase the numbers of contributions back to Roundcube.
It's possible: less protective lic. -> more users -> more contributions. But of course it doesn't always work this way.
From our perspective as a commercial entity, we have contributed quite a bit
of code for the 0.7 release, and might not have done that under a weaker license, as we prefer an even footing for all contributors.
So we would likely not agree to a less protective or balanced license.
I think we're discussing GPL vs. AGPL now. It's impossible (or almost impossible) to use other less protective license with current code base (and developer base).
