They don't care if their competitors backstab them. They just want web traffic to increase. They could just wait for everyone to buy an iPhone (or maybe a Blackberry), but that will never happen. They could have waited for Nokia, Samsung, Motorola, LG et al to make a better OS, but that wasn't going to happen. They could have waited for Microsoft to build a better mobile OS, but then Microsoft would make bing the default, and people might not remember to change it to Google. The open source strategy means that nobody is likely to gain complete control of the mobile market. That's good for Google. I'm sure Google would rather control the system, but it would be harder to get handset makers onboard.
