That's exactly it. Mobile apps are killing the web. Firefox OS was an attempt to combat that. This was no secret (e.g. https://wiki.mozilla.org/Booting_to_the_Web) but it's something that most people have overlooked. It was always going to be a huge challenge.
It's like saying desktop apps are killing the web which is stupid. You need both. Yes you need strong standards and open technologies but a random mobile game or a contact list on my phone isn't the web.
> Firefox OS was an attempt to combat that
It wasn't going to work anyway given the poor performances of Firefox OS. That's what killed it more than anything else. They chose to go for low end devices with web techs ? we all know how web techs perform in general, badly, compared to solutions based on Java, C , C++, Swift and co ... This true on desktop and even more true on limited devices such as phones.
Firefox OS is open source and it's a good think, but aside from open source developers,most buyers don't care about that.
