I know Roblox is not open source that's not the point. The thing is avoid sharing my account credentials with a third party software, if that software is not open source you don't know how they handle that data.
Inresting tool but I think Sober isn't open source yet, so until a full open source client comes out I'm not handling my account credentials to a third party tool.
Delisting a game goes against the point of game preservation. The trick of "buy it now to keep it" sounds like FOMO.
