It's good to get some more info, but it is a little disconcerting that they only mention patching Chrome. What was the sandbox escape on Android? Even if you had code execution inside the Chrome process on Android, that shouldn't be enough to enable persistence, so clearly there's another vulnerability.
Also in this case the attack vector was MITM of http and one time links as it was a targeted campaign, but it feels there's nothing preventing someone putting this in an ad campaign or sms/discord/matrix/whatever spam and spraying it everywhere to build a botnet or steal user credentials or whatever.
