'Owner of Russian social network offers Edward Snowden a job' is pretty clunky, and if you titled the article 'Pavel Durov offers Edward Snowden a job', it would be meaningless for 99.99% of its American readers. The title as it is does a decent job conveying the contents.
Or are Americans to be blamed for not knowing the owner of a social service hardly anyone here uses?
"Pavel Durov, founder of Russia's biggest social networking site, offers Snowden a job" could've worked. Of course "Americans" aren't to be blamed for this. I'm merely suggesting that they deserve better from media that is giving them a false culturally-superior image.
