What? I’ve never seen a metal 2L bottle. I’ve only seen plastic. I don’t believe compatibility “worldwide” is the reason at all. 2L plastic bottles haven’t changed in the USA for at least 30 years.

I’m pretty sure you misunderstood, the middle part of their comment is just talking about normal sized soda cans. As far as I’m aware 2L metal soda cans aren’t a thing.
