Say I take the keyboard software/app _itself_, rebadge it as ohmykeyboard, then sell it for profit. I would be violating the license in that case.
Just typing with it and using it on a regular basis doesn't violate that part of the license.
That clause is more intended for a situation where, for example, a phone manufacturer wants to include our app as a default option. That is the kind of commercial use we would prefer to negotiate and sign a special agreement for.
> You may use or modify the software only for non-commercial purposes
When one speaks of 'using' software, only one thing really comes to mind. Seems like an easy fix.
Wrote this comment with FUTO and it's pretty nice; it's certainly the first one I'm considering using over Gboard (because frankly the feature set of many FOSS keyboards is quite bad). While not FOSS, FUTO is a nice step up in terms of philosophy and actual license from most proprietary keyboards, with the exception of the commercial use restriction which really made me think twice about it.
