As I mentioned in the PMs that I sent out, GTM can get into serious trouble for distributing/containing illegal content and it damages our reputation with search engines if they find out that we are linking to sites that promote these activities.
RA2 isn't as big of deal just because none of the companies that were involved in its creation seem to care (I'm sure they are aware). There also aren't any more places to download the trial version of RA2 so you could consider it to be a try-before-you-buy type deal. We could request for them to make it officially freeware but (1) they may not respond and (2) they may ask us to take it down. Even if the latter is unlikely, it would be really damaging to the community.
