As I recall, Zuckerberg didn't provide any answers to the important questions that were actually asked during the hearings, but just said "Sorry" over and over.

I think it's pretty clear he had no intention of admitting substantial error on Facebook's part, come what may, and I think it's not likely that the outcome would have changed substantially had the questioning been longer or more intense.

Simply put, you can approach being questioned honestly, evasively, or in rare cases switch approach due to what is said to you during the questioning. I think it is well demonstrated that Facebook has chosen to be evasive as a core strategy, so the mere manner of questioning will at best serve to make it more blatant.
