It's about time operating systems actively stop generating unnecessary forensic data. When we delete a file, it should be overwritten with zeros, not just unlinked. When we clear browser history, it should be gone for good.
And many temporary files and other intermediate data should be stored by default in RAM, so when we power off the device, it is gone. When a device is seized it should not be possible to tell what the owner was reading or searching for. If the user wants to keep weeks of browsing history, that should be an opt-in choice.
Our devices should be working for us, not snitches or informants for the state.
