> there's no proprietary IP in your company's app

For most app that concept is "gone".

People routinely decompile and recompose existing binaries, and if you use "obfuscation" in your app it's still a small bump.

In today's age, IP is no longer a tangible concept that gives any advantages in software. What differentiates two businesses isn't their IP, it's their relationships and their moat.

Most vendors that had protected proprietary IP are now irrelevant within their vertical. What saves them are the protection provided by patents, which is public.
