It seems irresponsible to inject devices into your network that that indiscriminately MITM all traffic and can easily be configured to log passwords and auth cookies, no matter what setting you're in.
I'm not a big fan of these corporate MITM boxes that contain the keys to the TLS traffic of the whole company (which additionally often double as employees' private phones and laptops), but I do like to look at my own device's traffic.
That would be a pretty serious security incident from my POV.
