Buddybuild and very few other CI systems have iOS and Android support.
There are plenty of open source projects where the decisions and roadmap are decided in private and based on financial motivations. In fact most of the company sponsored projects are like this eg. Spark, Cassandra.
I'm a former Apache board member, and I've worked with contributors to those specific projects on governance issues. I stand by what I said.
When it is possible for users to become contributors and gain a governance stake, projects tend to become more dedicated to preserving backwards compatibility. People who are counting on the software get in a position where they can raise a big, loud stink when their interests are threatened.
Sometimes projects break compat anyway, but only after traumatic debate. And depending on how the open governance is set up, it can be nearly impossible for the project to be sold out from underneath its users.
