Actually, the opposite is the case.
Right now, the restrictive SA-licence keeps the community people from
creating better maps using both OSM data and other sources with other
licences. At the same time, the data ist not sufficiently protected and
any unscrupulous company or person can just grab everything and create a
much better map combining any sources, completely disregarding the
spirit of the licence. The community could not compete with such
multi-sourced maps and puplic usage would likely prefer the stolen, but
much more complete maps.
The new license will *enable* the community to create better works based
on OSM and as long as these are available for free, the evil commercial
cartographer has no leverage to sell his commercial products if he
doesn't add considerable effort and due to the DB-license everything he
adds is available to the community to build upon it, too.
