Yes, probably cos one of the news sites got sued by MGM... Poor buggers
If I remember correctly it was a german OFP fansite, they got sued for several thousand € as they had uploaded content of the OFP SGC mod and had ads enabled at the site.
The statement was sth. like that they were gaining profit from their website by said ads and thus were exploiting MGM intellectual property, if they wouldn't have used any ads it would have been ok.
But it seems the studios nowadays are more mod friendly, Star Wars Mods (e.g. for BF2142, Mount&Blade) were released as were LOTR mods (Medieval 2, Rome, Mount&Blade) while I remember a (very promising, I was browsing their site like daily

)LOTR Morrowind mod in 2003 or so being shut down because of legal reasons, same happened to a C&C Generals SW mod.
Also, armedassault.info has still the ArmA1 SGC Units uploaded and they haven't been sued in 2 years for that.
