No one thinks its free of any effort. But $10 wrist watches claim 100m waterproof (whatever 100m means in watch land). All I want is my phone's screen not to mess up when if my buddy pushes me into the pool. 2 ft of water for 10 seconds. That's it.

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.
