Right now their page https://upgradefromwindows.com/ just redirects to https://www.fsf.org/windows which has a wall of text and an infographic. Even I, who doesn’t have windows and will never reinstall it unless forced, clicked away from the page within 5 seconds. The FSF desperately needs help with marketing and design, plus it would be great to have tooling for brain-dead linux installation (no, find distribution, backup, put linux on a USB-stick, reboot, hit some button to get into the BIOS, select “USB stick”, reboot, click through installation, find alternative software, is not brain-dead).
IMO, the FSF unfortunately probably shouldn’t lead this campaign. They only endorse purely-FOSS systems, and that’s not realistic in the short-term future for most Windows users.
The FSF to me seems to be a predominantly ideological organisation, with little practical consideration
They do make a ton of practical contributions to open source development. But on the stuff they push beyond what the Open Source Consortium pushes, they should campaign those purities to intentional communities, not the general public.
