I do it out of respect for the mods and owners of this site. Discussing something like that in full could potentially cause legal issues and could cause problems for them from their hosting service. We don't want that to happen so I wanted to be very careful about what I said.
Seems a little paranoid to me...
1. There is no discussion of piracy whatsoever happening here.
2. There is no discussion of where to find such info here.
3. The software in question is not even a required update (as in, if you decline it it's not going to deactivate the operating system).
4. There is nothing in the EULA about allowing the OS to phone home beyond it's initial activation.
5. There is nothing in the EULA that mentions anything about any future updates being mandatory.
I can edit my config.sys file if I want to, and legally. And that is part of the operating system - "MS property".
I can delete any system file I want to, and legally. Deleting IO.SYS might not be a good idea, but I can do it, legally, and that is "MS property".
I can delete the entire operating system if I choose to. Legally.
True, there is a "circumvention" topic here, but I do not see where it's circumventing anything illegaly, or even unethically.
All that said - I've never had a problem with WGA and thus no need to mess with it.
