Very much as expected… fragmented, incomplete, and highly dependent on carrier. Google’s non standard E2EE extension will likely only work if messages are routed through their servers, which based on the observations here, even from the Android side it doesn’t seems to be routed through Google. Larger file means better quality pictures via green bubbles, anyone who’s sent/received a garbage and cares enough knows to send via third party messaging apps anyway, so nothing life changing here.
Let’s see if Apple applies pressure and push everyone to use Google’s servers for E2EE as they move towards iOS 18, but other than that… I’m still inclined to think the down play during keynote is apt.
