You can find scare stories about anything you want - the internet is a big scary place full of big scary stories.
At the end of the day almost no-one will...
a) hack into your wireless system,
2) decode your garage door opener, or
iii) hold you hostage and torture you until you give them the combination to your safe.
The OP was asking about the future of X10 and possible alternatives.
X10 works for some, Insteon woks for others and Z-wave, or UPB works for yet others - at my price point I use a mix of X10 and Insteon with the X10 being phased out as modules die.
Responding with scare stories is rarely helpful to anyone asking a simple question.
"I want to buy a gallon of milk, which brand do you like?" does not deserve a response of "you may get carjacked on the way to the store" or "HOOD once had a salmonella outbreak* so don't ever buy that" or "milk is taking food from the mouths of baby cows".
* this may or not be true, I use it simply as a reference to make a point.
Will you fine gentlemen now please stop, and give the OP some decent advice, or STFU and take your ball elsewhere
