Correction: only AnySoftKeyboard is open source according to the 0SI definition – an organization that famously did not invent the term open source but co-opted it from Christine Peterson, and which is primarily funded by closed source tech giants, such as Google, Apple, and Microsoft who are wildly conflicted in their interest as they profit heavily from open source software, according to the current definition while contributing virtually nothing back.
> according to the current definition while contributing virtually nothing back.
This argument looks a bit silly when even the most cursory research would reveal that many major and widely-used open source projects are most significantly contributed to by people working for these "closed source tech giants".
Coincidence? I think not.
