So, huge mistake in the article right away... It assumes total comp at Google is 110k..... The reason startup pay is nonsensical for many people isn't because startups don't have big upside, but that the upside didn't keep up with the massive increases in pay the bigcos have driven. Eg starting sde I comp at Google is 180k... , Or 60% more than the article assumes.
There is also value that bigco provides in terms of stability, benefits, professional hr (hr isn't your friend, but bigco hr will probably at least follow the law)....
Dan Lu's articles on startup vs bigco pay are well worth looking in to.
