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.
No, no we are not. But thanks for asking!
