24‑Hour Sideload Wait as Gate

Google will require developer identity, signing‑key submission, and a $25 fee for apps distributed outside Play, and will only let users bypass verification after enabling a buried developer option that imposes a 24‑hour countdown. The policy is presented as an anti‑scam measure (to disrupt social‑engineering urgency) but institutionalizes friction: spontaneous sideloading becomes slow and opaque, and developer identity becomes a prerequisite for distribution. — This reframes sideloading from a technical option into a policy lever: operating systems can enforce identity, fees, and time‑based friction to shape app markets, privacy, and political speech.
