I don't think you should be downvoted for this. The server chooses what to send me, and I choose if and how to display it.

Is it also considered unethical not to install that bundled spyware with your favorite freeware app?

Or how about that trojan installer tried to download automatically when you somehow landed on their page? After all, you used up some of their computing resources by serving you the page, you owe them the installation of their malware.
