Greenpeace is
embarrassed
because its director was commuting by airplane. However,
questions of which technologies to eschew personally for the sake of
the environment are not so easy to answer.
We can't end global heating by choosing to fly less. We need to
convince millions of others to fly less, for instance with a higher
tax on flying such as the EU
tried
to impose.
Burning fuel is not an act of oppression; it only becomes harmful
because of the amount we burn. This makes the right decision
about Greenpeace's own fuel use less clear. In the end, I think it is
important for the director to take trains, not because it will save
significant energy, but so he can set a better example.
In the free software movement, campaigning for users' right to control
their computing, we face questions that at first sight look similar to
those Greenpeace faces, but there is a crucial difference. Nonfree
program is not a form of pollution, it is an injustice. If you run a
nonfree program, the injustice towards you is independent of who else
runs it. Thus we say nobody should run a nonfree program and
nobody should develop one. For us to legitimize nonfree software
would be self-contradictory.
