Quoting Snarkasm

How you want your software to be used and how you dictate that it be used are two different things to me.

Void the warranty for opening something? Fine. That's no different than requesting that we be allowed to install software on non-branded hardware and not expecting support.

You can personally go install OS X on whatever you want. Go and make a company of doing that, that's an entirely different situation.

The free AV use on commercial computers is also less than relevant, since we're talking about the ability to use things we legitimately paid for. You didn't pay for the free AV; if you had paid for the commercial AV and they didn't let you install it on your home PC, that might be equivalent.

Free is the price though. You paid nothing $0 for it. If it was $.01 it's the same thing. You are violating their terms of use. They didn't give you the software you in downloading their software agreed to their contract. That is the same as when you install OS X. You agree to their contract. A commercial AV license that I bought and then sold to you as if you were another licensed user under my commercial license would be closer to what's going on and would still be illegal.

If apple only wants to support people installing OS X on apples that's their choice. You can choose to ignore that or not. Profiting off that is the question at hand.
