bottle works pretty much all the time. I know some people really do hate flatpak, but personally I hate steam more, so I'm doing anything I can to not depend on it, especially since both the launcher and the client itself are totally inaccessible to orca, the linux screenreader. The best way valve can remediate that, if they care which is a big if at this point, well, fairly easily, just update the chromium embedding to its latest version, or at least 4 versions ahead, then the web ui, the part the embedding is responsible for, will be as accessible to linux screenreaders as it currently is to windows ones. Not perfectly usable, but not a black screen either, that'd be a huge step forward, with little to no intervention from valve themselves.
