The problem is that this method disproportionately hurts people who don't have the time or energy to effectively hold two jobs (one full-time position at their day job and one as an independent developer or open-source contributor by night) because of family, friends, or some other facet of life beyond their laptop.

I think it's totally unreasonable to expect that everyone spend every minute of their lives coding or to have some kind of deep, personal connection to the code they write.

This thinking is ridiculous, and doesn't really appear in any other industry. Do you care whether your accountant's idea of an enjoyable Friday night is sitting at home making more spreadsheets? Would you demand that your eye doctor go home and craft her own lenses in her garage for fun? Competency doesn't require fanaticism, and no employer should expect that their employees devote their entire lives to their occupation.

If I want to code for 8 or 10 hours a day, go home and enjoy myself in the little free time I do have, then wake up and do it again, I don't see why that makes me an inferior employee.

This just seems like more misguided, unjustified cultural absolutism that is so prevalent in the industry.

EDIT: For those saying that the article doesn't necessitate spending massive time outside of work writing code, the author clearly conflates the two. "i have always been convinced that those who love code do not restrict their coding activities to their work. they take home that love and continue to create for fun as a hobby." Personally, I think passion could be a valuable heuristic in hiring, but the author seemed to imply that passion is only measured by your willingness to work outside of your day job. At the very least, that seems to be his expectation of good candidates, and his hiring process clearly disadvantages people who can't or won't code 24/7.
