EA you are violating your own terms

Sorry, but none of us actually own software like this. What we actually purchased was a license to run it and EA is entitled to change its own terms of service whenever they like. But the terms under which you obtained the Origin versions of those stuff packs are not the same terms under which one obtains disc versions. You can still go the disc route and avoid Patch 1.69 (before it's already happened), if you can find retail copies of them. And either way, there is no limit to one machine install per pack if it's for the same user, but the Origin way you just can't play the game (with the SP) on more than one Internet connected machine at the same time.

I've been on Patch 1.69 for a few months now and honestly, I don't like it. But EA has done nothing improper here, except to be annoying.
