% FIXME: installation information??

Another major goal for GPLv3 has been to thwart technical measures such as

signature checks in hardware to prevent modification of GPLed software on a

device.  Previous drafts attempted to accomplish this by defining

"Corresponding Source" to include any encryption or authorization keys

necessary to install new versions of the software.  A number of members of

the community questioned the impact and utility of such a definition.

The third discussion draft uses a different strategy to accomplish the same

task.  Section 6 requires that parties distributing object code provide

recipients with the source code through certain means.  Now, when those

distributors pass on the source, they are also required to pass on any

information or data necessary to install modified software on the

particular device that included it.  We believe that this will more

precisely accomplish our goals, and avoid potential problems with expanding

the definition of source code.  The new strategy should be familiar to free

software developers: the GNU LGPL has long had similar requirements that

enable users to link proprietary programs to modified libraries.

In addition, the scope of these requirements has been narrowed.  This draft

introduces the concept of a "User Product," which includes devices that are

sold for personal, family, or household use.  Distributors are only

required to provide installation information when they convey object code

in a User Product.  After some discussion with committees, we discovered

that the proposals in the second discussion draft would interfere with a

number of existing business models that don't seem to be dangerous.  We

believe that this compromise will achieve the greatest success in

preventing tivoization.

%FIXME: This probably needs work to be brought into clarity with tutorial,

%next three paragarphs.

Why do distributors only have to provide Installation Information for User

Products?

One major goal for GPLv3 is to provide developers with additional protection

from being sued for patent infringement.  After much feedback and cooperation

from the committees, we are now proposing a patent license which closely

resembles those found in other free software licenses.  This will be more

comfortable for everyone in the free software community to use, without

creating undue burdens for distributors.

We have also added new terms to stop distributors from colluding with third

parties to offer selective patent protection, as Microsoft and Novell have

recently done.  The GPL is designed to ensure that all users receive the

same rights; arrangements that circumvent this make a mockery of free

software, and we must do everything in our power to stop them.

Our strategy has two parts.  First, any license that protects some

recipients of GPLed software must be extended to all recipients of the

software.  Second, we prohibit anyone who made such an agreement from

distributing software released under GPLv3.  We are still considering

whether or not this ban should apply when a deal was made before these

terms were written, and we look forward to community input on this issue.

% FIXME: should we mention Microsoft-Novell at all?

We attack the Microsoft-Novell deal from two angles. First, in the sixth

paragraph of section 11, the draft says that if you arrange to provide patent

protection to some of the people who get the software from you, that

protection is automatically extended to everyone who receives the software,

no matter how they get it. This means that the patent protection Microsoft

has extended to Novell's customers would be extended to everyone who uses any

software Novell distributes under GPLv3.

Second, in the seventh paragraph, the draft says that you are prohibited from

distributing software under GPLv3 if you make an agreement like the

Microsoft-Novell deal in the future. This will prevent other distributors

from trying to make other deals like it.
