Am I the only person who thinks this is just fine and indeed a good idea? Minor tweak to lid manufacturing that aids recycling and disposal and is useful as a user of the bottle by ensuring the lid doesn't get lost. Though going by internet commentary it's apparently a huge imposition that totally ruins bottled drinks. May well be a silent majority thing? If many like me looked at it once and went 'huh interesting change, seems reasonable' they're not jumping onto to twitter to talk about it.
As for the subject of the article it's just an idea from a Dutch PhD student hardly a serious EU proposal.
