Hardly. It's linking to newsweek article, from where it gets the info about Giza and the picture, but is its own thing and has nothing to do with the supposed "original" of britannica (which is just a general piece on the 7 wonders with briefly mentions Giza, and says nothing about its surface, which is the topic here). It also features a NatGeo video on the topic.
It's also by a well-known website that does personal curation (not mere aggregation or mindless posting, and no shady SEO and other BS, to be worthy of the "blogspam" title). Kottke is a one-man-brand and has been at it for 2 decades...
You keep using this word "blogspam". I don't think it means what you think it means. (Or "blatant" for that matter)
"Noun. blogspam (Internet) promotional material posted to a weblog, often one specifically created for the purpose" -- https://en.wiktionary.org/wiki/blogspam
This definition makes it the very opposite of the post, since it's neither promotional, nor "specifically created for the purpose" of promotion.
At worst this is a personal blog site that posts interesting links and curates them. Don't know if you missed the whole 2000-2010 era, but that was a popular thing back in the day.
Sorta like a non-social HN -- where a single person selects the best bits and comments on them. Is HN "blogspam"?
Is anything that's not an original post "blogspam"?
If we were talking about automated aggregation, listicle sites, "link farms", etc, one could agree...
