You're blaming the end users. Most end users aren't aware of this stuff, and even if they are, have no practical way to evaluate quality in the way you've described. Even I, as a very technical person, could not evaluate if something is "hackable" without a huge amount of work, and not before I've purchased it.

Like similar cases (is this car roadworthy? are airplanes safe?), this is the classic case for regulation.
