Absolutely true. As a business they don't want to be in a position where they can be cut out of the ecosystem. That's actually an interesting facet of Android -- much was made recently about one of the open handset partners replacing Google with another search engine, but that's exactly how the platform is supposed to work. Google has no free in to all of the platform, beyond the add-ons like Google Mail that the partners would almost certainly want on the phone.
