The link from the PDF booklet targeted to those who would buy Microsoft's ad services:

https://about.ads.microsoft.com/en-us?s_int=en-us-gct-web-sr...

"Sign up for a Microsoft Advertising account to take advantage of these tools or get in touch with an account representative. If you already have a Microsoft Advertising account, log in or talk to your account representative about how to be a High Performer"

which leads one to, as the author writes, the page with the first picture of

"a couple of dudes snooping on animals, taking pictures and analyzing them while on Safari."

I don't think the choice of the photo is irrelevant.
