It's only a data issue if they're trying to reproduce google voice. Personally I got much better results from dragon naturally speaking 20 years ago than I get from google voice today, the cost was that you had to train it yourself first, but the benefit was it was trained for you, not "everyone". The later is the approach I'd prefer to see mozilla/OSS take.
That's fair. I think both approaches are useful in different situations. Mozilla seems to be focussing on Siri-like use-cases as opposed to dictation. Even for dictation, for many people having to train the system themselves is more work than they're willing to do. I'm sure what you want will exist eventually :)
