It's a fine balancing act between getting the latest updates and avoiding supply chain attacks.
I completely understand the author here, because I'm actually also leaning more towards avoiding supply chain attacks than jumping on the latest CVEs.
It's just a gut feeling, rooted in 25 years of experience as a sysadmin, but I feel like a supply chain attack can do a lot more damage in general than most unpatched known vulnerabilities.
Just based on my own personal experiences, no real data.
I'll try to put words to it, but a supply chain attack is more focused, higher chance of infilitration. While a CVE very rarely is exploited en masse, and exploitation often comes with many caveats.
That combined with the current state of the world, where supply chain attacks seem to be a very high profile target for state actors.
and those rare zero-days can be treated as the exception, and dealt with quickly. It seems backwards to optimize for dependency change reaction time these days with the supply chain such an attractive target.
