How would GPL change the outcome?

A lot of people say that it can prevent these situations but from working for large enterprises, a lot of the offerings that are created literally don’t even change the code. Thus they have nothing to contribute and have no obligation to release any source code.

GPL also does not prevent the corporation from building software in front of whatever GPL service it is. Kind of like the Linux kernel, why bother changing the kernel when you can build software in front of it and not change anything and thus have nothing to release.
