However, I think the original complaint is still legitimate. Why is Web Speech a thing, and what browser developers are poised to support such a feature, aside from Google? If Google wants to open source their speech tech, why don't they just do that?
I don't really blame Google, because they're just building a better browser than anyone else can build. But the effective result is definitely "embrace, extend, extinguish."
Perhaps it's not too late to refactor the web into a layered architecture so that it's possible to replace parts of it. But as long as we keep adding every feature under the sun, that goal is getting farther and farther away.
