I don’t hate flatpaks, but flatpaks require more disk space than the same apps from traditional repositories, and they only support a handful of the most common default themes. Since I only ever use older and slower computers, my disk space is limited, and I like to rice my desktop, I personally avoid them. But your use-case may differ.

You’re thinking in reverse. Walled gardens keep you in, not out. Without logging into your Steam account (pretending you don’t have one), try to download a mod for a game you bought on GOG and see how it goes for you.

This is silly. Valve is already a profit driven company. You don’t see the walled garden? The DRM? Valve supports proton because it’s in their monetary interest to do so.

It does not run well. You can’t see the performance difference between KDE and XFCE on neofetch, but you absolutely can on on old machine.

Source: I have an old computer.

Enable the chaotic AUR and you won’t even have to build from source.

Thank you for providing an actual answer. Most of the comments in this thread are condescending as hell.

This is a popular opinion outside of Lemmy. You won’t find many lowercase “l” libertarians here though.

How important is the Windows-style desktop? If the VM is designed for one thing and one thing only, I’d pick any minimal WM that can alt-tab, say JWM, and then just add Firefox and Thunderbird to the autostart file.
