Brave browser is very popular among the Linux community who appreciate very much privacy. Nowadays, a lot of amateur users try Linux. Many of them have difficulty to use the console in order to install brave and some of them that tried, made a mistake and damaged their distro sources file. This is not a great experience and many amateurs were asking for help to reset their sources file. I think it is imperative for the brave devs to give at least a proper deb packaging installation option in order to help brave browser spread (chrome browser comes with a deb installer).
PS: If deb packaging is too hard to implement, then please consider flatpak/snap/appimage packaging.
