I think that is highly unlikely +Billal DZ
- they make money from consumers in other ways, like charging for premium storage. But there is a very large market of free competition and they need to do everything they can to keep us coming back to the honey pot and create data to drive their ad business. Hence free stuff like search, Google+, Google Maps, Android, etc. etc.
AFAIK there is no one providing a a business class service like Google Apps with a real SLA for free now. And if you really want to roll your own knock yourself out setting up a mail server and trying to maintain and run it to anything near the level Google provides to consumers for free. I wouldn't wish that on my worst enemy these days.
