Each day it becomes clearer that Brian is the one to blame about the auto-tune thing
Yeah it's refreshing to hear Brian has no problem saying he uses Protools to pitch correct vocals. I remember a big discussion about this when NPP came out and even though Brian said he used it someone argued he didn't say he used it on vocals and that he may have meant he used it on instruments!
I noticed that from the interview but didn't want to mention it for fear of derailing this thread!

Well, there is still blame to be had (pointed at someone other than Brian) for an engineer or producer sloppily applying Autotune to the vocals. Yes, one could argue that Brian approved/signed off on the final mixes.
But the point being: Autotune is IMO basically ok if it's used properly and transparently. See the Gershwin album for an example of that. While there are still some trace hints of it on Gershwin, pitch correction was done with MUCH more care and finesse compared to NPP. Same with TLOS - I don't recall hearing any pitch correction on it off the top of my head. There probably is some here and there, but it's well done and doesn't stick out.
