That's certainly true. But, if you're planning on contributing large amounts of resources it's probably the situation that you can negotiate with the person asking for CA. Depending on the situation, you might be better off paying them to do that work instead of doing it yourself as they'd have an understanding there. Of course, that is *highly* situation dependent.

I think there is also many cases where creating a new organization makes sense. I think a good example of this is Linaro which is staffed to do "general ARM work" where the individual chip makers then have their own staff provide specialized features for their individual SoCs.

At the end of the day, business agreements are more confusing than why we have so many programming languages :-)
