Everyone uses smartphones. But to supplement the other good answers here, at some level of wealth, so much of your activities, interests and purchases are extended to secretaries, planners, asset managers, and otherwise individuals about whom you can claim “I’ve got a guy for that”, that tracking you as an individual becomes less effective.
Of course, nobody is immune just due to wealth and billionaires who use social media are tracked just like anyone else.








Side note: if you want to run a dedicated server and play on it with a cracked version (or just an offline mode or while MS services are down) edit the server.properties file and set
online-mode=falsefrom true. (Then restart the server if it was online)This wipes everyone’s inventories if there was already progress, so have everyone put their items in a chest before doing this. If you use modded, have everyone unclaim their chunks or any other username-bound items like teleporters with permission systems.
All of this can be redone, reclaimed, re-bound after the change happens. This effectively changes your in-game identities on a server from a Microsoft one to an offline one. This also makes it possible to evade username-based bans.
