I was surprised by this post. Mice are quite simple devices, and I've haven't used of on not working in decades. Logitech in particular are well supported on Linux. Logitech's page for the Lift even specifically mentions Linux compatability.

I do see that systemd broke the mouse support a couple of years ago (of course Poetteringware targeting init would break basic mouse support), but it was quickly fixed.

Perhaps you're referring to this page, and indeed Logitech is adding gestures to their firmware that is apparently problematic across OSes, and because they don't provide software for Linux you can't disable features to "fix" it as you can in Windows. However, that user found a solution for their issue and documents it.

Is the fix intimidating? It's editing some system config files, which with an influx of new Linux users may not be used to.

FWIW, if this mouse interested me, I'd not hesitate to buy it. It looks like the only issue anyone's complained about is related to how the firmware works, is also an issue on Windows, and there's a work around on both systems.
