Universal for any advanced civilization. Any species that would have the ability to find and observe the golden records would likely have to have an understanding of math to do so. Worrying about making sure dogs and cats can understand the writing on a satellite is not necessary when they will never even see it to begin with.

"flights in international airspace" was never the standard, and is a terrible attempt to remove all context from the situation. If you want to say sailing through international waters is aggressive, is every ship everywhere aggressive then? If not, how do you decide which ships are aggressive or not?

Are you saying china flying military aircraft directly towards a nation they regularly threaten to invade, with the intent to force a response, is not aggressive? Sure the US is acting in its own self interest, but acting like they are equivalent here is ridiculous. I absolutely can complain about a country threatening an invasion while at the same time saying those threats should be contested.

While true that it does extend over parts of china, that is never the part that is flown over. Most flights are coming from over water in northeast and southeast towards the island and are clearly aggressive, not just flying over their mainland.
