tastes totally different

Coke Zero actually tastes like (regular) Coke.

They won't change the taste of Diet Coke as there are people who like that and it has it's own market - it's seen as a separate brand / drink, whereas Coke Zero is marketed as a sugar-free version of Coke.

A bit like Pepsi Max vs Diet Pepsi.

Coke learned their lesson after they introduced "New Coke" in the 80s to replace Coca-Cola... very few people liked it, so they re-introduced Coca-Cola as "Coke Classic" (or similar), then phased out New Coke leaving just the original.
