"you fly over smoothly like a pilot" (so, with my view limited by the cockpit, and constrained to mandatory airways?)

"Everything comes from freely available geodata, straight from its publishers" (as opposed to using "freely available geodata" through mediators?)

"joined by thousands of open maps from the Library" (what Library? Of Congress?)

"Kugelblitz instances in the same network share it with each other if you wish" (yeah "if you wish" sure is how a human would phrase an optional setting)

"Kugelblitz speaks German and English and uses the units of your choice" (same)

and many more

It's slop writing.
