Lol, so WhatsApp and Telegram have the same, by their definition, vulnerability

Why though? Some of the biggest distros aren’t even based in the US but rather in Europe.

I don’t know the answer to your question (though I’n guessing their github isn’t the repo they actually use for development and thus could be a little behind), but Aurora and Google Play should have the same version, as Aurora just fetches it from Google Play as far as I know.
