Proton, the Swiss based, privacy focused VPN and cloud services provider does a $10 raffle for a lifetime accounts with all proceeds and a match up to $150k to a list of ten privacy/foss focused charities & organizations. Proton isn’t itself a non profit in need of funding per say but they do good work and it’s an easy way to put a small amount towards some worthy cause, and possibly win a decent product in the process. Wont post links to avoid looking like a shill, but the list on their page for the raffle might also be a good place to look if you’re wanting to donate to something directly.
