You could not be wrong about the hacking. It's an IP infringement and therefore illegal.

The foundation of your opinion is flawed. If I purchased a gun and ammo, and killed 100 school children is that OK because I "paid" for the gun and ammo?

What you are stating is that it is ok and acceptable to carry out illegal acts and cheat. The only point you are making is that you approve of cheating.

Do you boost and hack?

Ah ok, I totally misinterpreted what you were saying. I am with you on the hate of campers.

Equating camping to cheating is a rather flawed remark. Unlike boosters and hackers, they're not intentionally abusing functionality or exploits to gain their advantage. They're actively responding to a normal and aggressive approach taken by many in this game. If you're dying from campers, might I suggest you throw flashbangs, concussion grenades, C4, semtex, EMP grenades or the standard frag into a corner you suspect they are in.

Call of Duty is marketed as being a fast paced game, but that doesn't mean that only a single playstyle is acceptable. To assume that is to be extremely naive.
