exactly idk. about other EU Countries but at least in Germany outside of small country side stores you tend to have a very wide variety of "alternative" soft drinks. Some trying to emulate some big brand (e.g. Coca Cola) but also many keeping the concept (Cola) and putting their own twist on it. Most importantly most of them seem to be EU based (and often Germany based and sometimes local to your region).

The main drawback of them is that due to them operating on a (way) smaller scale and need to have a factor to differentiate themself, so most of them are more expensive. (but there are cheap no-brand clones, too).

A much bigger problem is that Nestle and co. try to either buy up any new innovative successful German food/drink companies. Sure after being bought up they tend to continue operate like before so technically they aren't dependent on the US, but they have been bought up anyway.

Nestle is Swiss, not American, so that seems like a very strange example to use.
