I am not sure why people were expecting tough questions in the IF interview. From the interviews I have read, IF does not really do 'tough questions'. You could say exactly the same of the Marc Jansz (KLM) interview. You have different styles of journalism. You can have hard-hitting 'call to account' type of journalism or you can have journalism which is oriented towards giving additional information and/or different insights. IF is more in the style of the latter, more Martin Bashir/Richard & Judy than Jeremy Paxman (these names probably don't mean much to non-UK FTers, but I am sure that you can substitute other names).
Randy's answer to point 1 raised by SAPMAN makes, IMO, this very clear. Yes, they can change the rules at will and don't need to give notice and, yes, they would not be the only ones to have ever done that. Are there many others who have drastically re-written the rules without notice or at very short notice, or indeed, virtually extinguished the program to replace it by a completely different one? Perhaps not. Now, if you are in the call-to-account style of journalism, you would probably raise that as a key issue. If what you want is to give a different insight/perspective, you won't.
Take IF as it is and judge it by the standards of what it seeks to achieve.There is nothing disrespectable about its style of journalism but it has its limitations, as well as its strengths.
