The same original public domain Landsat images can be downloaded from several
places, for example from landsat.org.  Then it should be OK to digitise features
forwhat ever purpose over them.  Unfortunately those images need to be colour
adjusted first.  I have done that for about 150 scenes around the Baltic sea
area and Scandinavia with Open source tools (GDAL and OSSIM) but it was bigger
task than I thought.
Same images are also available as very nice ready made colour balanced mosaics
from Geotorrent.org. Those mosaics are free for any use as well.  The "Europe
Landsat Mosaic" is missing half of Finland, therefore I started to make my own.

I think that what is uncertain with OpenAerialMap is if the imagery that is
colour adjusted by i-Cubed can be taken out from OAM, not if you can do derived
work based on it.  But who knows, perhaps being paranoid is the only safe
alternative.
