How about wrong-headed replacement of free apps?
Why did Google make GoogleEarth in the first place? After all, it started as just a rip-off of the free NASA WorldWind [http://worldwind.arc.nasa.gov/], and accessed the same free-for-everybody online datasets (mostly Landsat and USGS).
The answer of course is that Google gave GoogleEarth a different interface to WorldWind, and improved it in their own way, adding proprietary high resolution datasets and many user-oriented features. In the meantime, NASA improved WorldWind in other ways (on a miniscule budget), so that it is user-extensible, with lots of add-on packs available. You can even download all of the data for WorldWind, if you want to and have a few TB of storage.
