Dasani failed for a much funnier reason than just people thinking it was a ripoff. The specific circumstances were great, it was revealed to be just tapwater from the mains which became a scandal for a couple of reasons: firstly because bottled water was usually expected to be "mineral" water with some sort of selling point beyond convenience, secondly, there was a recall due to levels of bromate being over the legal limit. Lastly taking tap water and selling it as an upmarket brand while it was actually contaminated was literally the plot of an episode of the beloved comedy classic Only Fools & Horses, down to the fact that the actual Dasani plant was only about nine miles from where the tv show was set.

It would be like if some big flower shop tried launching genetically modified plants and it turned out that they ate people.
