Why is Spielberg so easily ignored from the flack?

An age old question for sure but I'll ask anyway, how come are Bay, Orci, and Kurtzman the ones mostly receiving the flack from the haters of Transformers 2007 and rarely Spielberg? Becuase correct me if I'm wrong but didn't he...
-Stay as executive producer for years?
-Choose Bay for director believing him to be the most perfect choice for the job and even after Bay declined he kept asking him till he changed his mind?
-Had ideas for the script, as original writer John Rogers said, and suggested to the writers for the main plotline to be the story of a boy and his car?
-Have a final say in things?
Didn't Spielberg also approve script verisosn for the film including the leaked one back in July 2006 which had plenty of fanboys scream bloody murder? And in the end when Spielberg watched the film entirely at Bay's hosue didn't he keep giving Bay the thumbs up? Besides the script part I beleive the rest was correct and if that's the case then such lack in the flack for Spielberg? Is it becuase he has done countless classics for cinema? Becuase to me that's a lame reason seeing as that it's almost never a good idea to completely approve and disprove a director and as much as I love Spielberg, he is by all means NO exception. Sorry if this is a little rude to some people, just a little steamy at the moment.
Now, I dug this movie and I don't care what anyone says, I like it. But just once I would like to see a huge bundle of people not only disown Bay and the writing team of Orci and Kurtzman but Spielberg also and no holding back on the flack Unless alot of people feel that if they did bash Spielberg they would loose plenty of credibility to their reputation online...That's one theory I have on this.
