IANAL, TINLA.

The laws that do or do not restrict data are different from those that
restrict software and cultural works.

Data may or may not involve a copyright and may or may not involve a
database right. This varies at least by jurisdiction.

Geodata providers therefore often use contract law rather than
"intellectual property" law to make their data proprietary.

In particular, if you don't receive the binary you have no claim to
the source. This gets obscured by the fact that most people just bung
the source on a public VCS or file server, but they don't have to do
this.

It may look like SA works require sharing more broadly than the GPL,
but SA only requires that members of the audience be able to copy the
work. This is comparable to only users of software being able to get
the source.

My lay person's understanding is that there may not be rights on the
data(base) in every jurisdiction that can be licenced so a contract
may be neccessary. Geodata providers are already doing this, and the
proposed licence would ironise this restriction in much the same way
that the GPL ironises copyright. Contract restrictions on Geodata are
not universal in the same way as copyright is, but they are
restrictions.
