Especially because Google's version is trained with illegally obtained user data (no, changing your ToS doesn't allow you to use previously collected data for new purposes in the EU).
We, as a society, should discuss if software trained on user data should be required to be available to those who have provided that data. If for software developed by training neural networks even any copyright can exist — or if it's by definition public domain.
Software trained with neural networks provides an immense advantage for existing monopolies, and makes it extremely hard for competitors.
If this trend continues, startups will become impossible for software that depends on being trained with huge datasets.
