'Tis the evil interwebs
I don't think the journos in question have a particular brief for or against Google or Facebook. I think they just know that they can blog for days about the latest internet spat and save themselves having to do some real work.
The biggest effect the web has had on older media forms seems to be a complete removal of the ability to prioritise something important over irrelevant tat and gossip.
This is to be expected in the online world where bloggers can't see past the end of their own obsessions but the print press only defence against becoming the junior media partner was lost when it turned against any remaining quality professional reporting and embraced the world of crowd-sourcing, blogging and social-networking.
So we end up with a bunch of self-referential and self-reinforcing cliques determining what is news and what the news is. They dictate what subjects are of interest and then they determine what the accepted truth is about those subjects.
Its hardly surpsrising that there seems to be less and less room for any middle ground between the fanbois and the haters - "pick your side and rant away" seems to have replaced "all the news that's fit to print".
