Requiring fees based on the deployment platform used does not constitute "free" software under any open source definition I have ever read.
So you have not read any, and have no idea what you are talking about. Start with the open source definition (opensource.org) and the Free Software Foundation (gnu.org).

You are making, unintentionally, an excellent point that one should refer to gratis software and libre software.

GCompris is always libre software, but sometimes not gratis. That is OK with both the FSF/GNU and OSI.
