\subsubsection{User Products}

\label{user-product}

The scope of these requirements are narrow.  GPLv3~\S6 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.

In brief, the right to convey object code in a defined class of ``User

Products,'' under certain circumstances, on providing whatever information is

required to enable a recipient to replace the object code with a functioning

modified version.

This was a compromise that was difficult for the FSF to agree to during the

GPLv3 drafting process.  However, companies and governments that use

specialized or enterprise-level computer facilities reported that they

actually \textit{want} their systems not to be under their own control.

Rather than agreeing to this as a concession, or bowing to pressure, they ask

here, since the main problem lies elsewhere.

While imposing technical barriers to modification is wrong regardless of

circumstances, the areas where restricted devices are of the greatest

practical concern today fall within the User Product definition.  Most, if

not all, technically-restricted devices running GPL-covered programs are

consumer electronics devices.  Moreover, the disparity in clout between the

manufacturers and these users makes it difficult for the users to reject

technical restrictions through their weak and unorganized market power.  Even

limited to User Products, this provision addresses the fundamental problem.

% FIXME-LATER: link \href to USC 2301

The core of the User Product definition is a subdefinition of ``consumer

product'' adapted from the Magnuson-Moss Warranty Act, a federal

consumer protection law in the USA found in 15~USC~\S2301: ``any tangible

personal property which is normally used for personal, family, or household

purposes.''  The USA has had three decades of experience of liberal

judicial and administrative interpretation of this definition in a manner

favorable to consumer rights.\footnote{The Magnuson-Moss consumer product

  definition itself has been influential in the USA and Canada, having been

  adopted in several state and provincial consumer protection laws.}

Ideally, this body of interpretation\footnote{The FSF, however, was very

  clear that incorporation of such legal interpretation was in no way
