Copy to Clipboard - ambush and abuse by javascript

Example on MSNBC:
http://today.msnbc.msn.com/id/29875493/ns/today-green/
Very frustrating -- but a violation of the user interface.

It is discussed by John Gruber on:

http://daringfireball.net/2010/05/tynt_copy_paste_jerks

"the site uses JavaScript to report what you’ve copied to an analytics server" when you perform a copy.
This I think seriously violates the function of Copy, and the user's rights.

Should browsers ensure that Copy is always a read-only operation, unless they have INSTALLED code to do something different?
