Do you have evidence for that? You don't have to name it, just say
"yes" if you know of examples; I'll believe you, even though it does
boggle the mind.
But of course encrypting locally and storing ciphertex remotely does
have an important drawback: without homomorphic encryption you can't do
"SELECT column FROM table WHERE ..." on encrypted database rows.
Fun,
