No, I’m making fun of people who are obsessed with ultralight (almost like a disease or virus), while also pointing out why people want something like this (ultralight backpacking).
Also poking a bit of fun at you (not maliciously) because if lots of people use these or similar designs in order to reuse the water bottle for drinking and they don’t get sick from it, then it’s probably not that big of a deal. No harm meant tho, if it’s not something you’re comfortable with that’s fine 👍
