You're right that it's a bad situation for millions of kids to be told to turn off security settings, it seems like that's a bad situation for Android/Google/Samsung than it is for Epic Games. It's kind of Google's own fault for tying their 'security' into a huge tax. If Google offered certification for a fixed cost then this wouldn't be an issue - you could distribute certified apps yourself and not have the problem. The problem is they tied certification into a tax and appearing in the appstore.

If you were more profit motivated, you might argue the problem is allowing externally installed software. Granted they foolishly obtained too large of a market share to have any say in that anymore.
If you care about users though, yes, the cost barriers for devs are a problem no matter who puts them up. Ideally the cost is in the phone purchase, not the continued use.
