One disadvantage of Embedded Linux -- Hackability? (Score 3, Insightful)

One thing that I think may detract folks from using Linux as an embedded OS is its hackability. For example, TiVo is now hacked 10 ways from sunday. As long as it's adding hard drives and so on, the TiVo folks have been pretty cool about it, but when the encryption scheme for storing recordings was hacked, that leaves them open to legal problems.

While proprietary EOS's are more difficult (for many of the reasons outlined in the article), they can be much more secure (in the weak sense of security through obscurity) than Linux.
