Nope, I'm well aware that it's possible to play them because the DRM is broken, but I'd grant you that you know more than I do if you can point me to an official statement proving they're "freeware" or F2P. As far as as I know, they're just as legally "free" as Abandonware or any other "free stuff" you can find on shady sides on the internet. Just as much "freeware" as "System Shock" etc. is. The fact that well known NWN community members have openly discussed it on the BioWare forum and that NWN connections now offers them for download doesn't change anything about that. Bioware and Atari have kept silent about it and it's unclear if they tolerate it or have just ignored the issue so far. It's also possible that Bioware turns a blind eye on it because they're not obliged to Atari anymore, but we don't know, and even if that's the case, it would still be a legal grey zone or even illegal.
So, yeah, you have a point, they're currently not "lost" to anyone who doesn't mind taking what they think should be theirs but for all I know they don't have the blessing of the license owners. I'd much prefer an official release as freeware or GOG package, but to each his own; other people might think the links helpful nevertheless, and I appreciate you telling them. :)
