It's not that it's bullshit, it's just that it doesn't encompass everyone which was the parents point. People who a) work on open source, or b) have enough free time that they're able to publish in their free time are the only people you want to hire? Great, have at it. But you'll quickly be wiping out a lot of people with experience behind them because they have a family. Some of them would have been the type to actually write code in their spare time when they were younger, you know, before github was around and before they had kids, they're probably still smart, but github isn't their CV and may never be. That said, code examples are a very nice thing to have, so it goes both ways.
