I think you want the opposite of a walled garden (app store). I think you want a completely open garden, such as we have with a typical Linux distro. A walled garden just changes the entities which can control your devices. It doesn't fix the problem of agency, trust, choice and consent. My tablets can't have spyware, because the drivers are stock open source. The folks making the hardware aren't in control of the driver software that runs the device. I can trust the community that any attempts to do this nonsense in an open source driver will make the news. The track record against spyware in the linux kernel is spotless. This kind of nonsense is only a problem with closed source software.
