While I welcome this decision, it is absurd that the law places any limits whatsoever on the act of examining how an artifact you legally own functions.

What they like to call "reverse engineering", because describing in plain language what is being forbidden would reveal what a severe limit on personal rights this is. Especially as we are being surrounded by devices where "reverse engineering" is the only way to determine what they do.

Such laws are no less than restrictions on what we are allowed to discover about our environment.
