Just wait when coca-cola and friends fill the skies with their own logo constellations when (not if) space technology gets cheap enough. After all, it only needs to be cheaper than conventional ad campaigns to be viable.

Imagine going camping or into sea and having a canvas of logos everywhere you look at during the night.

Nobody has to look at it right?

Dismissing this issue as "overheated silliness" is extremely naive and short-sighted.
