“3.3 Use Limitation” section of their licence file is not compatible with open source definition.

If you use iOS Strongbox does support passkeys.

We should support our fediverse admins and instances 💪 Support by sending money (for people who can), moderating content, submitting issues or helping the team and project ✌️

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

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).
