The rockers announced DeLonge's departure on Monday (26Jan15), but the guitarist blasted their statement, insisting he did not quit the band.
Barker is convinced his former bandmate spoke out because DeLonge could not "step up" and admit his lack of enthusiasm for the group caused a series of album delays.
The drummer tells Rollingstone.com, "I think he's just bummed because Mark (Hoppus) and I were finally honest... It's (DeLonge's statement) just funny to me. I think he's just in shock that he's finally been exposed. The truth is out. I just don't think he knows how to deal with it, so he says, 'I didn't quit the band. I'm booking Blink shows as we speak'. You're not the booking agent. We all know that's a lie. You don't want to twist any grown man's arm to do anything he doesn't want to do, but step up to the plate and say, 'Yeah, I don't want to play with those guys. I've been saying I'd record with the guys for the last two or three years and I'll just do Blink shows when I need money'."
Barker also questioned why DeLonge decided to reunite with his bandmates in 2009 after a hiatus, adding, "He didn't even listen to mixes or masterings from that record. He didn't even care about it. Why Blink even got back together in the first place is questionable."
