I really don't understand this article. It's like it's some kind of
surprise that GSM modems run firmware on their processors. It's so
obvious, yet everyone seems surprised and shares this article like it
was something insightful.

Probably you know this, but I feel like clearing it up to some other
readers that may be confused: This whole topic is exactly about such
"OS hiding in the modem" and I guess everyone who was following
Openmoko struggling with firmware bugs already know that it's buggy
and probably not very hard to exploit (AFAIR even some pretty standard
GPRS usage may cause buffer overflows).
