Murphy said that the fact the BBC left scripts "lying on a desk for a year and a half" was the real reason it lost big name stars to its rival.
"When the chairman of the BBC and the DG say talent only goes to Sky for the money, I thought that was so pathetic," he said.
"You think well paid talent will come to Sky for an extra five grand an episode?
"It's not because of relationships I have in the industry, forgetting the fact I commissioned Gavin & Stacey, forgetting the fact I'm very close to people like Ruth Jones. Not because of Lucy Lumsden working for us.
"No, it's because of money. It's s**t."
"I told her I'd love a British Roseanne and she came back with Stella. We went straight to 10 hours of episodes.
"It wasn't because we paid her more money... When the BBC said it, we laughed about it."
Continuing his rant, Murphy added that it was Sky's "clear vision" and "proactive work with talent" that was the real lure, rather than cash.
"Charlie Brooker is a pretty cynical guy. Do you think he'd come to Sky on Touch of Cloth for a bit more money?" he asked.
