In any country which took part on the
Berne convention, it is illegal to distribute copies of old software and games without the express permission of the copyright holder; hence, you can't legally download a copy of U7 or SI PERIOD. If you did, you
are breaking the law and
are a software pirate -- regardless of what the site you downloaded it from may have misled you into believing.
(There is, by the way, a special provision for distributing
your legally purchased copy of a software -- the
First-sale doctrine.)
While you may have issues with the current law, breaking it is not the way to get it changed. You can try pleading to EA to release U7 & SI into the public domain, try to rally the community into buying the Ultima games from EA and put them into the public domain or you can call your legislators and tell them you are unhappy about this law.
And that is final.
