This is the problem though, there doesn't even have to be a meeting. Google should be the leader and MANDATE the terms of using the Google Android software and infrastructure. If you don't like it, go build your own shyt on top of AOSP Android like Amazon and have to deal with all of the extra headaches associated with it.
They would eliminate 90% of the quirks of Google Android (unnecessary skins, stripped features, missing apps, late updates, etc.) if they made the manufacturers abide by their rules. Hell, the manufacturers could still develop all that dumb shyt if they want to. Just make it a post install option in the settings or Play Store menu. All Google has to say is you can't modify the base OS code without some good reason that will be integrated into future releases of Android for everyone. Most of the crap being done can be done through apps though.
Obviously this won't happen because they just need Google stuff on your device to get paid and don't really care about the experience though.
