I think you're actually agreeing with me here. I was disputing the claim that software should be made available in "a native package format", and my counterpoint is that devs shouldn't be packaging things for distros, and instead providing source code with build instructions, alongside whatever builds they can comfortably provide - primarily flatpak and appimage, in my example.
I don't use flatpak, and I prefer to use packages with my distro's package manager, but I definitely can't expect every package to be available in that format. Flatpak and appimage, to my knowledge, are designed to be distro-agnostic and easily distributed by the software developer, so they're probably the best options - flatpak better for long-term use, appimage usable for quickly trying out software or one-off utilities.
As for tar.gz, these days software tends to be made available on GitHub and similar platforms, where you can fetch the source from git by commit, and releases also have autogenerated source downloads. Makefiles/automake isn't a reasonable expectation these days, with a plethora of languages and build toolchains, but good, clear instructions are definitely something to include.
Windows 10. The reason I switched was pretty funny - I had previously bought a cheap SSD and moved my install over to it, and installed Arch on my HDD hoping to experiment with it.
I never really did that, but one day before Christmas my computer booted straight to Arch to my confusion, and after a while I figured out my SSD failed. I ended up installing gnome to have something to use in the meanwhile, since I wasn't gonna be buying a new SSD in the next few days, but then I just decided to stick with Linux. As I learned more about it I realised I was barely missing anything, and I preferred Linux for what I had.
