Totally agreed, That encourage me to stop buying/using plastic bottles. Quite challenging in Dublin where Everywhere you go water comes with plastic bottles/glasses, Ireland #1 plastic generator in Europe per person 61kg/yr [1].

Unfortunately, everything you can find close to the same form factor today is shoddily constructed and near-worthless.
We wouldn't need water-bottle refill stations everywhere, if the water containers themselves were more easily refilled. All the bottles are tall cylinders. Where did all the short, wide cylinders go?
I'm not sure I've ever seen the design you're referring to. And "canteen" style bottles are impractically shaped for existing infrastructure like cup-holders, etc. Maybe not crucial things, but definitely finicky.
The idea being keeping the barrier of entry as low as possible for people who are otherwise probably more resistant to the conditions you outlined.
I think this style is what was being referred to: https://www.amazon.com/Stansport-Aluminum-Scout-Canteen-1-Qu...
This particular item does not appear to be well made, which lends credence to the difficulty of finding a high quality product.
You have likely never seen the shape I am referring to.
At some point, someone decided to move the caps to the cylindrical sides, rather than keep them on one of the round faces, and then you couldn't fit the thing under a bathroom sink faucet any more, and a drinking fountain needed a bit more arc to fill it. Difficult fill locations might only fill those up halfway. This was likely done to accommodate blow-molded plastic canteens, and to manufacture from flat and rolled sheet metal, rather than pressed.
So now, even if you buy a "real" canteen, the cap is pointing in the wrong direction, and you might as well just have a large, awkward bottle.
