I somewhat disagree with the article only because as a co-founder and also as early engineer in previous startups I've worn the interviewer hat a lot and candidates with solid github portfolio projects demonstrated to be better suited for the role than those that didn't have projects to demonstrate their skills. I agree that there are a ton of 10x engineers that don't do any public open source stuff but at the same time you'd know they're good just by having a conversation with them or reading posts they've written. One of my previous employers has also expressed that they were impressed by my github projects and I feel like that gave me leverage over other candidates. It really depends on the employer and I think the larger the company the less they care about your open source projects or how good your portfolio since there's a lot of churn and they can afford it unlike early stage startups where they do a little more diligence on early hires.
