Isn't it a little convenient that the backdoor was installed after the data breached that supposedly happened before that, according to Yahoo, and also that the backdoor was installed after the USA Freedom Act passed? I'm starting to have serious doubts about whether it's even true the backdoor was installed in 2015 and not earlier. Also, Yahoo started implementing email encryption early 2014, so I would imagine the government would want a workaround as soon as possible. The data breach supposedly happened in the fall of 2014, after Yahoo had started implementing encryption.
