I think a good first step would be to require all public services and similar to transition to FOSS software only. Schools, governments, public health, etc, should not, generally speaking, be in the business of making money for private interests, nor should our data be stored in these black boxes. If we don’t own it; it owns us. Sure that’s a huge departure from current reality, but I see it as fairly clear cut. I’m sure people will say I go too far.
