@miren I would like to be able to use foss software at my school but I don't think anyone would allow it and they still use non free software and will continue to for years to come I think.
@miren https://privacyinternational.org/ may have done something specific - but all of their work would be relevant
@miren FSF comes first to my mind. https://fsf.org
Framasoft is, in my knowledge, the organization who first raised public awareness against GAFAM and offered libre solutions. https://framasoft.org
