If it is becoming more difficult to obtain information by way of the FOIA then I think the wider public should be concerned.
Not necessarily. The Acts have been very useful, but are at great risk of becoming a disproportionate burden on authorities. Noting up the ICO case law regularly, I see time and again circumstances suggesting exactly that it is abused. Personal vendettas seem common. Half wit and lazy journalists looking for a manufactured headline are also common (see the BBC fairly regularly).
I have no way of assessing just what the balance is, but the Act represents a fairly blunt nosed and artificial attempt to transcribe a very vague and general feeling that 'we ought to know' into law.
Discussions here have suggested an unrealistic view of the cost of complying with these requests.
To be fair the cases also reflect some particular authorities who treat requests with general contempt.
