Startup idea:
Form a company that explores new markets in legal liabilities. It could bring lawsuits with little risk where the payoff could be billions of dollars. Off the top of my head:
* Research whether channels were engineered into smartphones to allow water to leak in (since they have no moving parts and should self-evidently be watertight).
* Find the planned-obsolescence parts in things like car doors that were engineered too thin or out of plastic so that door and window handles fail after a certain number of uses.
* Find evidence that companies opted to use proprietary battery and charger form factors which drove up prices and prevented interoperability.
...the list is nearly endless. Most of these seem like they depend on research or whistleblowers. If the free market and regulations won't prevent this kind of widespread hacking then maybe lucrative opportunities could be found working within the courts!
