Distribute a software product to a third-party that they can load onto
their own hardware.

The license is designed to cover circumstances when you are
distributing a product to another party or modifying the source. Even
the GPL is free for you to use out of the box for your own
applications. The strings kick in when you distribute a software
product to someone else to use on hardware you don't own, or modify
the source -- even for your own use.

The "modification" clause is why many businesses do not use GPL
software. They can't modify the source, even for internal use, without
their own work being encumbered by the GPL.

It is sad that there are not more high-power database systems under
BSD or Apache-style licenses, since these complications do not apply.
If you distribute ASF software to a third party, you must acknowledge
our copyright and license, but the software is otherwise free. If you
modify the software for your own use, under the Apache License, your
work is still your own.

If you are distributing a product to others that includes GPL
software, and you don't want to put your own work under the GPL, the
end-user has to download the GPL package separately (e.g. MySQL) and
then plug it in. (And you also have to be careful about how the
plugging in process works.) If you distribute the product as a
ready-to-go bundle, then the viral aspects of the GPL kick in, and
your package must be GPL too. :(
