I feel that only big apps are worth side loading, because only they have enough reputation to evaluate (like Fortnite); it's the small apps which have a credibility problem.

I think small apps will even have a credibility problem on the official Apple app store, because, say, let's just consider an app which tries to be a better calendar. You download the app and you don't like it, but your entire calendar data history has basically been exfiltrated, and could be worth far more than whatever the price of software. This is true for almost all apps which would normally be seen simple and innocuous. Contacts. Mail. Messages.

If we don't solve this credibility and privacy problem, I can't see how small players should compete in a way which is harmonious with user privacy concerns. This makes me only want Apple to have more domination. Domination to force every single app vendor to use Apple Pay. Domination to force every single app vendor to support Apple's anonymous account registration process. Domination to abide by Apple's new demands to inform the user of tracking.
