It's useful to a security researcher or privacy advocate looking into what an application like zoom is actually sending around. It may be also helpful when reverse engineering "proprietary" protocols, e.g. to create compatible clients. It may be even easier to just "mitm" the traffic like this in applications you develop yourself to find out what going on deeply buried in some third party library. Easier than modifying the code or attaching a normal debugger. There are plenty of legitimate uses.
