@rvlobato while I'm a Firefox advocate, I also don't really see an issue with this. Chromium is open source, but that doesnt mean any associated services like Sync have to be made freely available. Google are looking out for google, and having complete control of the browser market would be a huge advantage for them. If you don't think they would be suitable custodians of a browser monoculture, then don't use their browser (chrome or chromium) while that is still an option; also give Mozilla some money.
