I do think it's important to remember even if someone shares her jet information, which is publicly available radar information, it's not like a random person can get anywhere near her considering the security they have around private airports and private jets. And that's before they have to deal with her own security. I do understand why she doesn't like it, but if they post it 24 hours later then she really has no reason to complain.
I'm sure the Cease and Desist letters will be enough, but bringing up her private jet just isn't a great PR move right now, it's just drawing attention to how much she uses it. (And I say all this as a major Swiftie)
