To build on what John and Bill have said, every product has to have some place to store its data (base files, service updates, build lists, etc.). Decades ago it was decided that each product would have its own user ID created to store the data. Each product could have its own installation/service scheme (SES and the Shared File System hadn't been invented yet). Further, it is possible to have multiple releases of a single product installed, and each has its own set of files. Keeping them separate is much easier when the disks are owned by separate user IDs.
