BinaryFormatter serialization is dangerous. There's nothing about the "binary" part of it that makes it dangerous. It's absolutely possible to have safe binary formats (protobuf, as you suggested) - and it's absolutely possible to have dangerous text formats (NetDataContractSerializer, which is XML-based).
BinaryFormatter absolutely has its problems, but it's not the "binary" part that makes it dangerous.
