I use Heliboard with futo voice typing
unfortunately Futo seems to only be source-available and not libre software :/
though I can +1 the Heliboard recommendation! idk when they added it but it finally has a multilingual keyboard function :)
You can use the FUTO kwyboard free of charge for an indefinite period of time. Nothing in their source code will stop you from doing that. The people behind Futo even stress this point. But if it’s software that you find value in, they ask that you purchase it for a one-time fee. It may not be Libre Software, but I don’t think that’s unreasonable.
that’s the thing though, it strips you of the options the four essential freedoms provide.
and imo it’s not rly an argument. Libre software is free as in freedom and not necessarily free as in beer. You could license it under the (A)GPL, charge for downloads in the Play store or for compiled binaries on ur website and ask for donations on F-Droid.
You could even do a freemium version where some features are locked in the binaries you distribute and need a license from ur website or smth (for those who don’t want to use Google Play). (iirc SD Maid 2/SE does this)
