The article is full of anecdote and false implications. So, "Yahoo told employees they could no longer work from home." If you are working from home because you're taking care of your children, I think it's fairly reasonable to expect that your attention is split and you won't be as productive. Much of it describes the work habits of top execs. I don't think that's representative of the industry as a whole, and probably aligns pretty well with work habits of top execs of other industries.
