The difference is labor time compensated for is compensated for, labor time expropriated is not.
Labor time compensated for by Google excessively well is also labor time where workers are producing wealth excessively well. Ken Thompson had a hand in creating an enormous amount of wealth before he stepped foot in Google. Where does all this created wealth come from? The work done by those who work and create wealth at Google (and the uncompensated primitive accumulation of web content - and the taxpayer funded grants to Stanford and for ARPAnet development etc.)
