Twitter has been updated so that you can't post a link to @mastodon.social@elonjet's Instagram account. Just tried it for myself.
ADSB is intentionally unencrypted public data. That's how ATC works and it's a key to the #AvGeek and #PlaneSpotting community.
You can even track military planes (including AF1) when they have their #ADSB transponders on. ADSB is optional for military, and required for everyone else, even entitled and whiny billionaires.
