Is this referring to WebRTC's use of DTLS-SRTP? Because, if so,
"end-to-end" is a bit misleading given that today's implementation of
DTLS-SRTP there is vulnerable to to MitM attacks from the service
provider.

Well, it's end-to-end. It's not end-to-end with authenticated peers.

Sure but isn't that a core promise of and what's really meant by end-to-end? Without that constraint SDES would also qualify.

Quoting wikipedia:

"The intention of end-to-end encryption is to prevent intermediaries, such as Internet providers or application service providers, from being able to discover or tamper with the content of communications. "

There's currently no such protection in WebRTC's current DTLS-SRTP implementation.
