Again, as shown here: this license covers *software*, not *data*.
Data is fundamentally different from software: for example, there is no
"source code" for DE405. There is just no "preferred way to edit" for
such a database -- these database are created from observation and not
thought to be edited by hand.
So, it is just wrong to apply software licenses to databases like DE405.
