I agree with you. My dream is that every public school should use and contribute to FOSS and FOSH, but I'm an utopiste. Honestly I wish Serif would at least free some of its codebase but that's very unlikely. I would like to have these proprietary software as I still rely on them for my workflow on a GNU/Linux machine rather than macOS and that sounds more reasonnable for a private company building private code and selling licences. Today it's some of the few software that I can't run on GNU/Linux to ditch a proprietary OS for work.

I have finally ditched Windows years ago after living my whole childhood in that proprietary crappy spyware environment and did tried many FOSS tools for professionnal work and I do use some (PenPot, blender, OBS, Thunderbird, VSCodium (and Zed a bit), LibreOffice, Nextcloud, UltimakerCura and Signal to name a few).

Unfortunately I still do rely on proprietary software (and these rely on proprietary OS) and yeah there is a reason for that : I need to get the work done. They have the money proprietary licence advantage over FOSS tools of course but hey a small part of the money I make thanks to these proprietary tools are sent to foss projects I want to support. It's not as big as I wish and I don't have enough time nor skills to contribute as much as I want to the Free World in general but I do my part and it has grown over the years.

I would prefer relying on proprietary solution on a free OS than relying on proprietary software that rely on proprietary OS. That's why I signed this (probably useless) petition.
