A big difference: As a user I could "feel" whenever a Java Applet was loaded. Suddenly everything became slow and only rarely the GUIs were acceptable. That diminished reputation in users, aside from security problems etc. With WASM the user doesn't notice it. Without looking at dev tools you can't tell if some of the functionality is coming from wasm or JavaScript/typescript/.. In consequence users won't develop the "yikes, Java" reaction. wasm got the chance to slowly creep into stacks.
