I might be out of touch with security nowadays, but could there be a reasonable explanation on Microsoft’s part here in that they wanted to try and help prevent the dime-a-dozen malicious attachment attacks that we’ve all heard about? Don’t get me wrong, I’m no stranger to Microsoft’s strategies— opt-out telemetry, Cortana, bing search in the system tray, etc. It’s not all fueled by just this one particular propriety that I brought up, I know it’s also got a lot to do with their way of pushing their products onto their users with annoying opt-out (at best) features that everyone might not want, that serve to push whatever it is they’re trying to sell to their users.

Point is, at least this specific gripe, for what it’s worth I can see some valid justification for. And if this is new behavior that they intend to stick with, I wouldn’t be surprised if they did improve it over time (although I also wouldn’t be surprised if it stayed as much of an annoyance as you described— bing search in windows remains an unchecked crime against humanity to this very day!)
