The news that there is going to be a Firefox Operating System has set the cat among the pigeons. GigaOm has an interesting take on it which is refreshingly alert to the irony of the carriers’ response to the development.

The fact that the carriers are lapping this up represents a moment of supreme irony: these are the same companies – largely former monopolies – that were all about walled gardens, the companies that wanted to replicate the portal-first, AOL model in the wireless world. And what happened to stymie that scenario? Apple happened.

It was the iPhone that really loosened the carriers’ grip on their product. Suddenly they were just providers of voice and SMS and data, not suppliers of value-added services. The revenue cut from app sales now went to Apple and Google, not to the operators. The walls to their gardens had been obliterated, and someone had set up much more attractive walled gardens elsewhere.

So back we come to this idea of the open mobile web. This is an area where luminaries such as Tim Berners-Lee have been on the warpath, pointing out very real problems with the iOS/Android model. These include the inability to share app-based content in a standardized way, and the inability to search across apps. In short: the loss of the level playing field that web technologies represent.

Firefox OS is designed to solve those problems. Weirdly, we can now witness the former walled garden proprietors genuinely extol the virtues of openness. By promoting Firefox OS, they cannot regain control – however, they hope to prise some control from the hands of Google and Apple.
