Waze won the best overall app award at the Mobile World Congress in Barcelona. This might have raised its valuation since the Apple talks were publicized - http://www.globalmobileawards.com/winners-2013/
If they are doing due diligence now, they would need to look into the GPL source code. Waze (at least in the past) was based in part on RoadMap which is GPL - https://github.com/mkoloberdin/waze/
That was version 2-2.4. Now they are at version 3.6, so maybe they rewrote the relevant code.
As far as the R&D centers, this can't be compared, because both those companies (Snaptu, Face.com) were much smaller than Waze. Facebook may be interested in an R&D center in Israel too, and is just looking for an appropriate base on which to build it.
I guess this seems to put Facebook more on a collision course with Google, after Facebook Home.
