> If highly skilled individuals like blue-collar technologists and programmers collectively withdraw our human resources

Individuals cannot convince the Subway app, Raycast or LastPass to defect from Apple or Google's platforms. Using those platforms is an executive decision, and Senior iOS/Android engineers will not voice this minority concern or risk their job to advocate for it. Similarly, Apple and Google's platform monopolies are not designed by individual engineers, but executives that will happily pay to replace you if you feel morally unjust.

The only place where this could work is indie development, since that's the scale where developers have authority to sabotage themselves. And sabotage themselves they would - it would be like Fortnite's removal from the App Store except with ~100,000 times less public outcry. You'd go bankrupt before ever inspiring change on the platform.

Nothing about the technology changed, indie developers have long warned users to not give their OEM control over what they can install. But users don't really care, businesses told them the App Store is "safer" before they ever got to see the alternative.
