I think you are being incredibly harsh about the licensing structure, they are simply trying to make sure companies with keyboard apps like Google don't steal their work out from under them by adding in a non-commercial clause. Lots of companies have this Elastic Search License, Business Source License, etc. There are numerous companies who have used permissive licenses only to be horribly burned by companies stealing their work out from underneathe them and they have subsequently used non-OSI approved licenses.
Why is it such a bad thing for developers to license there work however they please in a way that fits with the goals and values of their individual project? Here the keyboard maintainer wants to use a license that isn't FOSS, why is this so concerning to you that they have opinions which differ from yours?
