There is a petition at http://petitions.pm.gov.uk/iplayer/ imploring the Prime Minister to "prevent the BBC from making its iPlayer on-demand television service available to Windows users only".

While the government doesn't have any direct control over the BBC, they can certainly raise questions about the commercial impartiality which the BBC is supposed to practise.

I'd encourage all UK citizens, even Windows users, to sign up. The problems with the BBC's existing proposals run far deeper than merely restricting access to Windows users.
