I think this strategy makes sense, if you do an overall push to have all software sources verified. Knowing users, a simple warning that an app is unverified rarely affects their behaviour. You need to hide the app, to encourage app developers to get verified for it to work. Users ideally should be able to trust by default, because we can’t trust them to know any better.
I could never figure out why they do it. You want to be far south and have an open ocean to the east of the launch site.
Why are they not launching from Hainan or somewhere on the south coast, west of Hong Kong?
