+1 as person interested in Linux on Steam.
But I definitely do not 'demand' anything from devs. Games on Steam are clearly marked which OSes they support. Linux is not one of them. Almost Human is currently 5 guys, but the coding is mostly done by 2 of them, while the rest working mostly on graphical side of the business. Their time is limited and they have huge list of various requests. They happen to very creative, so they may have an idea or two on their own as well

While getting Steam on Linux would be nice, there are requests that are of higher priority, and will provide better results.
Like it or not, but steam support is just usability improvement. You can install custom mods, subscribe and comment on them without Steam support, just it is slightly less convenient. I very much prefer devs would spend their time on fixing bugs, enhancing API to do new things, so modders could get even more creative or simply continue their work on LoG2.
