What if "provider" is a euphemism? If they're intercepting and decrypting all traffic to and from the "providers", they have to write code to actually extract the data from those streams. Such code would "vary by provider", and an analyst could make "special requests" for code to parse a certain kind of data from the stream. The timeline of providers entering the program could be a timeline of when the NSA wrote the code to extract that company's data. Also, the published slides are just three out of forty-something. The bottom of the slide that lists the capabilities says "complete list and details on PRISM web page." I agree that if they're doing this, they probably are already intercepting all unencrypted SMTP traffic.
