shmerl: Both of those reasons go against DRM-free approach which should give the user full freedom of how to use the package. Users want to do weird stuff like playing it with VLC? It shouldn't stop them from doing it! That's the point. Putting any kind of password protection or worrying about potential torrents is already falling into the DRM mentality.
If has nothing to do with DRM-free or not, You are talking here about extracting the content of the installers, something never officially supported, on an not officially supported system (for the game in question at least.).
If GoG tomorrow decide to use their own proprietary installer because it's more convenient for them, are you going to say that the games are suddenly no longer DRM-free because it's no longer possible to extract the installer content with an open source tool ?
And even without going that far there are plenty of setup maker who don't have any extractor available, if they had use something else than InnoSetup you probably would have never been able to extract the content of the installer to begin with.
shmerl: Yet you know perefctly well that many users don't use "supported installation mode" and unpack their games with other tools. Which often happens for systems which don't have Windows / Wine. For example to play those games on mobile systems with ScummVM. Why should users go through the pain of finding Windows just to unpack those games in such case?
Well because they don't use the supported installer and want to play the game on a non supported platform, so it's perfectly normal that it's them who would have to go through the extra pain if they want to do so. It's not GoG job to make sure they games and/or installers works/are extractable on all non-suported plarforms.
If you buy the windows version of a games and want to play it on an Android device, then it's pretty understandable that you will have to jump through some hoops to make it work and that you will most probably need to have a computer somewhere.
shmerl: . Yesterday you said there will be no DRM. Today we got this password. You say today you won't make it harder. Should we believe it? We are talking about the attitude here, not about the method. Once you are falling into that mentality, there can be no end to it. So please, revise this approach and remain community friendly by avoiding any such stuff. You don't need to support it but you don't need to be hostile to DRM-free approach either, which is exactly what's happening in this case.
It has nothing to do with DRM or being hostile to DRM-free; you can still install the games on any computer, the game nor the installer phone home or anything of the like. It's just a case of an unsuported tools no longer working to do something that wasn't supported in the first place; like I said earlier if tomorrow they decide to no longer use InnoSetup to instead use something else, you might end up in a state where there won't be any tools, free or commercial, available to extract the installer content, but it won't make the games any less DRM-free.
