user9382: https://blockchain.info/DecryptWallet.html has been removed for quite some time. Anyone know why?
PS. FWIW, an archived copy at Pastebin

user12835: Have a look at https://bitcointalk.org/index.php?topic=594570.0 for ways to export your blockchain.info wallet to another client.
As for the why, at this point I would say it has to be bad organization or possibly lack of funding. Blockchain.info has been fundamentally broken for quite some time (a quick search yields a post on bitcointalk over a year old for a still unresolved, somewhat minor problem: https://bitcointalk.org/index.php?topic=271633.0 and if you do a bit of digging you can find plenty more)
