I think what TBL is basically reiterating is the time-honoured idea that "information wants to be free" [as in speech, not beer], no?
Surely, the OpenGraph is FB's first acknowledgement of this same idea and an attempt to avoid losing relevance over time in the same way that the AOL walled garden did.
If TBL is concerned it's because the web looks like it is starting to evolve towards closed networks. In fact, I very much doubt it is. It only looks that way because, so far, iTunes & FB have few credible competitors who are challenging their model.
Diaspora (no affiliation) will be one to watch.
