Proprietary batteries are the reason thin electronics exist. You can't use 18650s to make a MacBook.
I think the problem here is that you vastly underestimate how hard manufacturing is. The things you're proposing are like me trying to sue Facebook because it crashes all the time. Is it annoying? Yes. Is it because they're actively trying to subvert me for nefarious reasons? No, it's just because they don't know how to do it better in a reasonable price range.
Speakers are trivially sealed, as are buttons. They are just a fancy electromagnet, or piezoelectric crystal.
Also both can work through induction potentially keeping them outside a "pressure chamber" and forgoing sealing altogether. Although I just want the steam of my shower not to mess up with my phone, not dive 100 m with it.
Not to mention sockets for SIM and SD cards. If you can take the back off the whole phone to change the battery, that makes it a lot harder.
Quite a few phones are waterproof or splashproof : http://www.techradar.com/news/best-waterproof-phone

There’s no way in hell car companies are purposely under-engineering things to cause them to break. That damages the brand reputation, and will drive the next sale to a competitor.
Yes, they make engineering tradeoffs. No, they don’t design a part with the specific intention that it will fail earlier than a comparable (cost-wise) design would.
Either way, it wasn’t intentionally designed to do that. There was no engineer that said, “Hey, let’s juice our parts revenue in 5 years by making this hinge really weak.”
EDIT: Thanks for that article, though. I could see myself getting suckered into a good deal on a Benz. Now I know why the price is so low.
So maybe these things aren't as widespread as you'd think... at least not in a legal sense. I'd also like to think that maybe people aren't "designing" flaws into things rather than finding the maximum economic benefit, or just are "naive" to what they design.
Sort of like a patent troll, but for good? I do like it.
I think there's always a danger of having this type of litigation be abused (in this case I'm also thinking of drive-by litigation around the Disabilities Act etc.)
edit aww spitfire beat me to the patent troll punch.
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!
