One of my favorite coincidences is how the mapping startup has the same name as NRO’s series of orbital surveillance platforms: https://en.wikipedia.org/wiki/KH-11_Kennen

This is also where the “K” in “KML” comes from (Keyhole Markup Language)

Probably not a coincidence. The Keyhole name was in the public realm prior to this. (It'd been used within the intelligence community since the late 50s.)

I believe it was an intentional reference

Except a court decided they didn't.

This company didn't have a claim on the idea of 3D visualization of the planet.

By Jury. And at the time Google was a highly popular company. I still think a lot of large companies get away with stealing the candy from others.

But Keyhole did not steal anyone's candy. The origin for the product (and I'm paraphrasing the story here, secondhand) was actually SGI'ers had developed a method for efficiently rendering gigantic textures at multiple levels of detail. They looked for the largest texture they could find for their demos, and that turned out to be high-res terrestrial imagery. This demo app then turned into the Keyhole product itself.

This technology was developed inside the world's leading computer graphics company, where people spent 24/7 thinking about how to render 3D graphics and textures better, faster, at higher resolutions. And Keyhole was merely a 3d app that happened to be showing the planet. The other company did not have a valid claim against that.
