I'm pretty sure he knows what he's doing and it costs what it costs for a reason.
It's possible $166/mo is not enough of a hit on his income so as to be worth spending time optimizing (unlikely considering how little time it'd seemingly take to optimize), or since he works for AWS it could be sponsored (which would mean he has to justify the continued cost to his bosses when they ask about it).
All valid reasons, but not technical ones. Either there's some aspect of implementing this that we're not thinking of, or there are non-technical reasons involved that we're simply unaware of.
Thousands of people have built that for the past 20+ years without posting a link.
