Shipping source code with business logic (assuming the definition of source code includes obfuscated JS) is how the entire web works today! With WASM the code that is shipped will be even further away from the original source code and really not so different from downloading ARM from the App Store or Java/ART bytecode from the Play Store.

Not the entire web. eBay and Amazon don't put all their algorithms in the browser; PayPal doesn't either. They hide their company jewels behind their API where they're a little more secure. What you see in the browser is the presentation layer code.

Hybrid apps could achieve that same kind of relative business logic security, but at the cost of pushing more and more of the actual business logic behind an API and not in the JS in the app. At that point, the benefits of code sharing (such as they are) get fewer and fewer since it's really pretty easy to write API code in Objective C, Swift, Java or Kotlin.
