Generally speaking, I agree, but for three example locations that were given in the article, that's not the case. Google's offices tend to be in major cities, especially more liberal ones, and those often have good public transit. Both Seattle and NYC have more people who commute to the city center via public transit than by car; I'm not sure about the numbers for SF.
I agree 100% that 2 hour commutes are crappy, but a 2-hour commute on a nice form of public transit is very different than 2 hours of being stuck in traffic and stressed out.
