In his own words ...

Don't read the media reports on Blair's speech. Read what he actually said:

My principal reflection is not about "blaming" anyone. It is that the relationship between politics, public life and the media is changing as a result of the changing context of communication in which we all operate; no-one is at fault - it is a fact; but it is my view that the effect of this change is seriously adverse to the way public life is conducted; and that we need, at the least, a proper and considered debate about how we manage the future, in which it is in all our interests that the public is properly and accurately informed.
