Pardon me if this question is stupid; I am not a native speaker and perhaps I am oblivious to certain nuances of English. That said, didn't the author mean this piece to be titled “Google launches the ultimate job killer?” Singular job?
When the cotton gin was invented, it didn't just take a few jobs away, it eliminated the position of cotton picker. Nobody does that job any more because a machine was just too much better at it. (It probably invented a new position for the person who runs the machine, but that's a different point.)
In a historical pre-echo, Ely Whitney spent a lot of time and money suing planters for making illegal copies of his cotton gin.
I think in this case, though, I suspect it's used semi-intentionally because the plural "jobs" is more of a political buzzword than the singular. The issue is jobs, not any individual's job.
