No, the token and secret are used to sign the request. Someone who MITMs
your connection can read the traffic, drop it, but not pretend to be you
to the API server or modify it. I've done this in testing of a local API
proxy. There are some attack vectors with oauth + HTTP that remain open,
but not ones which involve pretending to be the user or stealing

The redaction bot was written before HTTPS was fully available, and I
believe it also talked over a local network connection to the API
server. I should change it to HTTPS at some point.

The advantage is that it avoids the editor knowing the user's password,
or storing the password.
Personally, I'd like to see HTTP basic auth removed as an authentication
option in the future. All apps *should* be using OAuth.
