Well, the whole point of TFA was that it's not really that easy to distinguish between the two notions, even if you consciously understand it.

That is, the employeer can use the "nice food / ping pong table" etc, in order to get people to work for free (unpaid overtime, crunch marches, uncompetitive pay, etc).

None of which are true for Google, which actually encourages healthy worklife balance even though many people don't take advantage of it. Google has many non-product related company objectives, for example, increasing the number of women in the company, or improving work life balance. Younger people without kids tend to avail themselves of the on-campus resources and stay late, I myself leave at 6pm. I do not sacrifice time with my kids in the evening for the sake of free food. (In general, I don't believe Google HR/People Ops believes that # of hours worked = increased output)

Here's the thing, you've got your view of the world, of Google, and then there's the reality, in which Googlers tell you that your model doesn't match the facts, or that Google is consistently rated one of the best places or work, or that Glassdoor rates Google in the top 50 companies for work/life balance. A sweat shop of induced labor via sweets and candy it is not.

But oh yeah, I might be completely brain washed and believe Larry Page is my best buddy, that's why I spend my nights on social media and hacking on game code, and not working on finishing up stuff at the office from home.

Thanks for the free gifts Larry, I promise from now on I will work long overtime hours for free.
