Well google does not allow any access to Android's RCS API, and basically uses a non open source extension for encryption. So yes, if they wanted RCS to not be their own little fiefdom, they would've just done so. Theres absolutely no reason to not allow access to the API except for lock in. I think only Samsung has a deal with them to actually be able to use RCS in their messaging app.
I didn't ask if they thought Google were reliable champions of openness. I asked if they believed Google would not work with Apple to diminish Apple's lock in. Screwing 3rd party apps long after Apple did doesn't show Google would have not or would not work with Apple.
