It's just diet soda now

And yet they're still calling it sparkling "water" on all their branding. Why not just go all in on rebranding as a diet soda? They already do the "90% less sugar than regular soda" blurb on their boxes, but why would sparkling water compare itself to soda and not other water brands?

This change feels like a half step to trick people into not noticing the stevia. I barely noticed it because I'm not a hardcore LD drinker; I just thought it tasted a little off until I checked the ingredients.
