Nope. He has not. He's still Sony. The Amazing Spiderman 2 after credits was an advertisement, nothing more. Fox had a deal with Marc Webb, the director of Amazing Spiderman 2, that he couldn't go work for their competitors on comic book movies. Sony managed to convince Fox to release him from that contract. However, in exchange, Sony had to put a promotional advertisement for DoFP at the end of ASM 2 for free.
