[HelloImSteven]

Hard to say. As a hobbyist with access to several OSes and hardware platforms, I appreciate the differences between each and enjoy the process of finding the right tool for the job (or building new ones where they don't exist yet). Interoperability doesn't necessarily benefit me. But most people aren't me and don't share those interests, so interoperability helps enable equal access to software, content, communication, etc.

I have no personal issue with being "left out", being unable to install specific software on specific systems, and so on, and thus no personal issue with Apple (or others) enforcing barriers in those areas. However, interoperability of major OSes and platforms would provide the greatest benefit to the largest number of people, so it just seems logical to me.

I don't "care" about interoperability, but I agree with it.
