It is about economics. The attacks on crypto systems have complexities, and still at the end of the day they require things like raw calculation power. Could they break even single 16384-bit RSA key pair? Probably yes, but they wouldn't be doing anything else on that year. It would be simply way too uneconomical.

Presented by Spiegel are internal services that are designed on purpose to be more economical. They exploit more bad implementations. It doesn't really matter as long as the dirty tricks get the work done.

Also, NSA seems to troll for targets from the vicinity of their targets of interest. It is again more economical, and can be just as revealing. The risk there is that the broken target has nothing of use. The real movie style "let's break the encryption keys" stuff is done for sure targets when they get the extremely rare high value target on platter.
