So you're basically saying that Facebook will open-up because Google may force them by using their quasi-monopoly, pulling an IExplorer versus Netscape on them.
However, I have my doubts that this will work, quite the contrary - Google may have GMail and Youtube, but while Google was experimenting with shoving Buzz down on Gmail users' throats, Facebook was busy becoming a platform. Which is the reason why Facebook is now on its way to become THE identity provider for the Internet, the reason why Facebook is the preferred method of login for services like Foursquare.
And unfortunately for Google, the trust of other businesses in them has been eroded in time. For example, only Google could piss off an entire category of businesses by crawling their content and presenting it as its own, with graphical results on the first page of any location-related search: http://www.google.com/places/
It's a shame really, because if Google was considered a benevolent-dictator of the Internet, than trust itself would have been enough for third-parties to consider integration with them. In this instance however I'm seeing other online services just picking Facebook, as while they are evil, at least they are the ones with soon-to-reach 1 billion users.
Youtube integration will be awesome, but that's not enough when the rest of the Internet is on Facebook. Also, checkout what Facebook did with pictures uploads. They are effectively killing Flickr. I'm seeing them doing the same for movie uploads ... they probably haven't felt the need for doing that, seeing that the preferred way of distributing Youtube videos to friends is Facebook ;)
Ahem, you may be too pessimistic. I actually like the fact that Google is challenged on social content. When you have so many great people and you are challenged on an issue, it can give interesting results.
For instance, I am no fan of most of the changes in search (eg. Instant, Snippets) but I think that adjusting search result rankings to the "+1" of my circles is a big deal in long term. It makes "+1" an actually useful button. I now start using it as "intelligent bookmarking". Except if you believe in near future people will search Internet through Facebook or will not search at all, which I don't, then this little "+1" feature is a big leverage against Facebook.
Google are also challenged by Amazon with their platform, and I would be surprised if they did not prepare some thing on this side. It is just that, with Buzz and Wave, they learnt that one big company like them is not a start-up and therefore can't "release early, fail quickly, iterate" (as so often advocated here on HN). So we, observers, would better be patient.
Don't forget Chrome. It seems to me that this is an incredibly fast entrance in browser market, and really did shake things up, for the better. If Google, through its browser and mobile OS, find a way to make life much easier for open social network users, Facebook may have to comply. It would not be stupid for Facebook to be open, they would still have the biggest number of users, and their revenue should not drop just because they allow other social content provider to access their data openly (as long as they continue offering a good user experience).
