“Any program that scans all the mail that Yahoo has access to would have scanned this email,” Gillmor wrote me in a message.

“If Yahoo chose to segment their scanning by limiting it only to mails that have ‘@yahoo.com’ email addresses [and omitted those sent from @rogers.com], of course, then they would have chosen to exclude this email from the scan,” Gillmor continued. “It’s not clear to me whether any such constraint was in place, though.”

“I’d imagine that, yes, the program would have applied to Rogers customer emails, unless Yahoo elected to specifically exclude them,” wrote Marczak in an email.

Yahoo declined to comment on whether the alleged system filtered out emails from Rogers customers.

Tobi Cohen, a spokesperson for the Office of the Privacy Commissioner, confirmed that Rogers consulted the office in the wake of the Yahoo hack. But as far as the possibility that Rogers customer emails had been siphoned into a surveillance dragnet goes, “Given we don’t have detailed information about the matter, we are not in a position to comment,” Cohen wrote.

When asked if Rogers was aware of the allegations against Yahoo or if the company is concerned that a backdoor could have affected its customers, spokesperson Garas referred me to Yahoo’s statement and wrote that “as such, we believe this matter is closed.”

Great to know that Rogers thinks it shouldn’t (or, worse, doesn’t have to) explain how one of its contracted service providers may have grossly violated the privacy of Rogers’ customers.
