As far as I can see, nobody here has made any claims regarding anything being illegal in the US.

What kind of evidence do you want exactly? This is crystal clear to anyone with the most basic understanding of the GDPR.

That’s not evidence. That’s just your opinion, based on your assumption that private aircraft are like private cars under the law.

Except that they have never been treated equivalently in any legal venue or government regulation.

Do you have any evidence to share which might suggest that GDPR treats private aircraft differently than ... literally everything else?

If not, why would we just not accept that GDPR treats aircraft exactly how it treats everything else? The law, as written, clearly offers no specific coverage or exemption for any types of vehicles.

As the one making the assertion of illegality in terms of the GDPR, the onus is on you to provide a substantive justification for it. Not me.

I've already done that.

You're the one arguing that there's some special exemption for aircraft, but have done nothing to substantiate that claim.

Besides, with the GDPR it works the opposite way. You have to justify why your data processing is legal, not the other way around.

And for fucks sake, neither of Flightradar24 or ADSBExchange even offer a GDPR-compliant privacy policy. ADSBexchange does not offer one at all.
