Strauss rightly should be embarrassed about his comments, so stupid to say anything like that when you're in a comm box, whether you think you're on-air or not. Completely different to private text messages sent to KP's friends too, where the contents have never been 100% proven or verified.
As for KP playing for England. I'm as big a KP fan as anyone, but realistically, he's been on a pretty steep downslope in his career the last few years. Average has dramatically fallen, especially in ODi cricket, and his Test record hasn't been good enough. Also, it's plainly obvious to anyone thats watched him bat recently that he's massively out of form. In the innings I've seen him play his timing has been off, he's looked scratchy, and nothing like the player that was dominating between 05 and 11. I'd be happy to continue watching him turn out for England if they'd not kicked him out of the side, but now he's out, there's no way back. He's not playing enough cricket, and not scoring runs when he is playing, obviously has issues with the captain and coach, his body is falling apart, and has been a shadow of his former self in the last 3 years. Moving on from KP is definitely the right decision. He's the greatest English batsman of his generation, but his time has passed, it's time to move on and find someone to replace him.
