The game has not been freewared. Often designers have games that they worked on available on their sites, even though the company that the game was developed or published under owns the IP to the game. Al Lowe does it, Mark Seibert and Christy Marx does it, but none of them has a legal right to do it. Activision probably has no idea that these games are being distributed for free and may not care about some of the older games, however, they would be in their legal right to sic their lawyers after them. If anyone really wants the link, please do it through more private means.
