Though small, plastic bottle caps and lids contribute significantly to Europe’s nearly 26 million tonnes of plastic waste generated yearly. Much of this waste becomes marine litter, with plastics making up approximately 80% of the debris in our oceans.

I know you don't yet have oceans in Switzerland, but that bit of discomfort is worth it, imho. If you don't like it, get a glass (hori or verti, your choice) or your trusty Sigg.

It's not just that, the tethered caps are usually redesigned versions of their untethered ancestors. As such, they often use less material than the original version, making them cheaper in the long run.
