Google doesn't care about any of this, otherwise it would have been fixed in 2010. But if you really want to add them their e-mail addresses are:
vicg@google.com
page@google.com
The calendar is going to be replaced by Timely, the next generation version (more feature-rich then the current one) Bigtop will replace the GMail interface.
By the way, I'm adopting https://code.google.com/p/j2objc/ ASAP -- yesterday, if it were possible. I was just contemplating writing my own C++/jni bridge but I'll take what already works, especially if it's being battle-tested by Google. :)
Edit: And with bugs like https://code.google.com/p/j2objc/issues/detail?id=224 I'm considering changing my mind. My Java code isn't that great either, and a few classes with JNI might go a long way compared to hacking together ObjC from Java code. The hard part that neither directly addresses is how to integrate Gradle-powered flavours and build types with Xcode/iOS targets and simple macro keywords. Sharing language files, string/config values and some assets... all seem project-specific at this point and not very well generalized.
Ah yes, fun when your CEO's email address is the same as the name of a product. I worked on +Pages, and we'd constantly be adding +page@google.com to discussions in Google Docs by mistake. ^_^
I wouldn't be surprised if there are hardcoded rules that guard senior Google execs against such inadvertent (or by design, take your pick) communications from hoi polloi that uses their products.
A whitelist wouldn't work, because these people need to be contacted from the outside, from people with gmail addresses (usually goes through a secretary though)
A dedicated (unfiltered) internal email sounds more likely, or just routing directly google.com to google.com addresses.
But then again this is google and maybe internally it's only Hangouts
Just in case anybody took parent seriously, you shouldn't do this for the same reason you shouldn't flood their email inboxes about this. They will just mark your calendar invitation as spam.
