I agree 100%. Still, I dont think most people will donate until they have to and this will lock those out who cant and drive those away who rather sell their privacy. Maybe lemmy (and other foss) should go full wikipedia mode and have banners all over the place until you donate even a dollar. I donate 1$ a week (not the only project I donate to either).
Then, on the other hand countries should have programmes to fund this kind of stuff and it should just happen by user count.
