Choice: it's one of the key ideas at the heart of free software.  The right to choose how to use your software, the right to choose who you share it with.  Who could be against choice?  Certainly not the Initiative for Software Choice, except that it has a slightly different view of what choice implies:

To encourage continued software innovation and promote broad choice, governments are encouraged to consider the following neutral principles:

• Procure software on its merits, not through categorical preferences

• Promote broad availability of government funded research

• Promote interoperability through platform-neutral standards

• Maintain a choice of strong intellectual property protections
