It would be funny if the state of packaging on Linux would not be so pathetic.
If authors care about Windows they do produce Windows installers and/or publish it in their store.
If authors care about macOS, they produce .dmg or publish the app via Mac Store. Additionally they often publish it on Homebrew.
If authors care about Linux, they provide packages for Ubuntu and Fedora, and sometimes for more distros from the long tail (usually Debian comes 3rd as it is simple to add after Ubuntu).
