Harm reduction is important.

Normal sodas are pretty acidic - coke has a pH of around 2.5

Soda water has a pH of 5-6.

Your saliva has a pH of around 6-7.

Water, of course, is at 7.

Remember we're dealing a log scale here, and that going from 2.5 to 5.5 isn't a 2x improvement - it's closer to a 1000x reduction in the amount of acid. If replacing soda with soda water is what gets them to stick to it, that's what they should do.
