That's true for a recipe that was developed in a past millennium. Trade secrets are still very much relevant for companies that work with more modern technologies than soda from before the Great War, and a useful protection against competition. Even if you do believe that companies within the US or EU wouldn't touch other's IP with a 10 foot pole due to strong laws, you'd have to be very naive to think this is valid in all parts of the globe.

Edit: it's also trivially not true for trade secrets in the legal sense -- if you upload your trade secret willingly to AWS, it's no longer a trade secret, unless you have extra contracts in place. With obfuscation, you could skip a lot of red tape to keep it secret.
