Grandparent comment by beckler says they were trying to make some IoT product. That will be deployed in situations where that happens; if your customer has a MITM set up, you just nod your head and sell them something that works in that setup. You can't say, "MITM should be illegal, please buy my non-auto-updating solution anyway and stop it with your MITM."

Good thing beckler found this while eating their own dogfood due to their own network being that way. Imagine that everything worked fine in their environment and then so customers came back with this issue. Then they would be beavering away hacking up their own core snap or whatever.

Seriously, you can think of no reasons?

Many competent companies MITM employee traffic to scan for malware, leaking confidential data, etc.

Should you not be able to MITM your own machines?

In your own company you're free to do what you want.

I can understand the reason for this. Now that most suppliers treat their devices as 'black boxes' and call home to install updates whenever they want, the security team no longer has visibility nor control over this. So much stuff runs Linux which we don't manage but still has to have full access to our network.

And public repositories have been compromised and spread malware in the past. So yeah I totally understand this, even though as an enterprise Admin it's a total PITA to manage the root CAs.

For some situations, it's called for, but it's a huge pain in the ass. I am in a similar situation, and I need to patch every docker image I use. It's terrible to deal with, as an engineer, but the information security team does catch and eliminate a lot of content-based attacks.
