This is silly. Common Voice is not adding NVidia-specific features; what would that even look like for a database? There is no comparison to be made between donating resources to an openly licensed database and encouraging developers to optimize their games for proprietary APIs.

And the assumption the shutting down Deep Speech was specifically for NVidia's benefit seems like a fairly large leap to me, given that Deep Speech is already mature, still being developed under Coqui.ai, and surrounded by a wide diversity of other deep learning projects that also aren't controlled by NVidia.

Decreasing barriers of entry for those models and providing raw data is probably the right thing for Mozilla to be focusing on right now. Any team can build a language model, only companies like Mozilla can coordinate mass data collection for those models.
