Quick synopsis - Japan Boeing plane suddenly
depressurizes at 36000 feet.

Capt does a quick "death dive" to low
altitude to save everyone from suffocation.

Do planes not have those drop-down oxygen masks anymore?

Yes, any plane flying at that altitude likely does have the drop down
oxygen masks but they are only good for a small number of minutes (I
think it's around 7-10 minutes.) So the plane does need to drop to a
lower altitude quickly (around 10,000 or less). Now does that qualify
as a "death dive"? No, but it sure sounds more exciting and will
generate more clicks.

That only happens if they were in a flat spin during the dive.

Because the lack of artificial electricity cancels out your momentum.

That goes without saying.

 Sorry I said it.
 Can I say instead that any moving water is always safe to drink?
 I’ve been seeing these annoying commercials for magical hoses that because
they have a copper end all contaminants and toxins are removed so you’re
drinking absolutely pure water.
 I can’t imagine what possible mechanism could do this especially given that
the water or at least most of it doesn’t actually touch the copper and it’s
only in the vicinity of the copper for a fraction of a second.
 If this works, why don’t we have copper nozzles for our faucets at home?
 Hell couldn’t California put a big copper nozzle on a hose coming out of
the ocean and end all your drought problems?

Copper has long had an alchemists' claim of curing arthritis, ague, the blahs, etc.  Hence those ubiquitous Copper-Fit commercials for wearables that infuse the metal into socks, tea-cozies, etc., without actually mentioning its "curative" powers.  (The FDA is listening.)  It's nice to hear they've moved into plumbing, where copper does at least have some historical health benefit of replacing lead...
