So abandon open source and move to “post open source” or ethical source might be a (sad) solution.

Did you have a look on ethical licenses? For example, Coraline Ada Hemke who created the Contributor Covenant (famous code of conduct) started few years ago the Organisation for Ethical Source promoting “ethical” licenses defined by seven principles.

So in fact this third family of licenses is not open source nor free (as defined by OSI and FSF), nevertheless I feel some needs or willings in your side to go, let’s say, “one step further”.

In ethical licenses you can find for example 999 ICU, ACAB, Anti-Capitalist, Peer Production, Hippocratic or some BSD 3-Clause variants about nuclear topics.

You can also have a look on that slidedeck (in French, sorry).

I do not know if the solutions I listed below are open source ; however as an open source contributor I am used to work with some tools depending to choice of the projects:

• Crowdin
• Weblate
• Loco

About credits, I don’t think these tools exposes in some automated way the contributors identities. However, nothing prevents you to use these web UI tools to find who contributed and list people for example in your CONTRIBUTORS files. Another way could be to edit the automated commits these tools submit to your Git repos by adding credits to the translators (with for example Co-authored-by field).

An app? Nope. For notifications, there is open source alternatives to Google and Apple services but it is used in the apps side, not users side. Have a look on microG and Open GApps to flash in your Android device; it might help you.

It seems the “radical” organisations like the FSF or the OES were right and more legitimate in the end.
