Пока что OHA — скорее маркетинговая ширма, чем что-то решающая организация. Вот, например, что пишет Karim Yaghmour в своей свежей книге Embedded Android:

A Word on the Open Handset Alliance

As I mentioned earlier, the OHA was the initial vehicle through which Android was
first announced. It describes itself on its website as “a group of 82 technology and mobile
companies who have come together to accelerate innovation in mobile and offer consumers
a richer, less expensive, and better mobile experience. Together we have developed
Android, the first complete, open, and free mobile platform.”
Beyond the initial announcement, however, it is unclear what role the OHA plays. For
example, an attendee at the “Fireside Chat with the Android Team” at Google I/O 2010
asked the panel what privileges were conferred to him as a developer for belonging to
a company that is part of the OHA. After asking around the panel, the speaker essentially
answered that the panel didn’t know because they aren’t the OHA. Hence, it would
appear that OHA membership benefits are not clear to the Android development team
itself.
The role of the OHA is further blurred by the fact that it does not seem to be a full-time
organization with board members and permanent staff. Instead, it’s just an “alliance.”
In addition, there is no mention of the OHA within any of Google’s Android announcements,
nor do any new Android announcements emanate from the OHA. In sum, one
would be tempted to speculate that Google likely put the OHA together mainly as a
marketing front to show the industry’s support for Android, but that in practice it has
little to no bearing on Android’s development.
