They shouldn't be using "every". It sounds like the kind of thing American programmers say.

Some people still thinks words should mean what they mean.

The irony that I've written a typo in a comment about words is not lost on me.

I personally thought the interesting part of the submission was the "every" of the title, ie there might have been some AI algo that could have somehow approximated height and shadows based on multiple satellite images or use some data that is not available for everyone (hence the "every" could have applied)

Currently it's an approximation of shadows based on unreliable open data which is nice but not that special.
