GeorgeSoros Goal is to use meta, x and other normal apps but hopefully with far more privacy protection than using them on stock Android.

Meta and, to some extent, X are in the behavior monetization business. They observe what you watch, who you follow, etc., and try hard to tie your behavior to you.

This is why people are working so hard on alternatives to those systems, such as Signal, Mastodon, etc.

What you use is up to you, but sharing behavioral data with giant behavioral-profiling companies will probably result in your behavior being profiled.

GeorgeSoros Waze may well work better than OsmAnd. That could be because Waze has a giant developer team that is well funded... by ad revenue... based on behavioral data... such as location tracking. To whatever extent Waze is in the behavior business, they don't really care which OS you are running, as long as they are collecting information about where you drive and when.

GrapheneOS can protect you against accidental vulnerabilities in the Waze app, and it lets you control which contacts are shared with Waze. But GrapheneOS can't stop you from providing Waze your location tracks if you choose to.
