I dunno how you drink out of a bottle, but I most certainly don't deep throat it to have its neck in my mouth. Please enlighten me how it would make it impossible to "drink properly" when the bottle is flipped beyond the neck.
I have problem with 0.5l yoghurt bottles. Yoghurt is best when shaken before opening the bottle because its viscosity spreads evenly, otherwise you get watery yoghurt on top, bottom is too dense.
I enjoy having morning breakfast in the park, drinking yoghurt straight from the bottle. When I shake it, yoghurt sticks to the cap. When caps were removable, I'd put it aside so that yoghurt that stuck to the cap does not spill on my shirt, re-screw it after I finish and throw bottle and cap to the bin. Now it's hard to remove the cap and I spill yoghurt on my shirt frequently, so I go to greater lengths to tear the cap away and re-screw when I empty the bottle.
I do not know what it means to "flip a bottle beyond the neck".
Tetrapack milk packages have some sort of a "roof" on top. The opening is on one of the sides of the roof. It is hard to drink from that anyway, now additionally the cap is pressing against the lips.
You don't have to "deep throat" a water bottle either to feel the effect. The cap always disturbs.
It is also ugly of you have water bottles on a dinner table with the cap hanging on the side.
It is also harder to screw the cap back on.
But like in the EU, criticism here can just be flagged and then it never happened.
