Windows, Mac? Bundle your own updater. Or use Steam. Download one file and run with a click.
PlayStation? Nintendo? Submit it, wait about two weeks, and out it goes.
The Linux desktop is single handedly the worst distribution platform for an app developer, both in fragmentation and being unable to update your own software. The Linux desktop also had the arrogance to claim developers should do it their preferred way; and to harass devs for using tools like Flatpak. Then they wonder and complain and can’t understand why devs refuse to make Linux versions even for cross-platform frameworks.
The idea that someone like Adobe should make a package for each distribution, and negotiate with each distribution if they are sending out some ancient version of Acrobat, was a stupid power-trip philosophy on day one with none of the clout required. Even Apple doesn’t reserve the right to stonewall releases purely because of version numbers.
