It's very likely that you can't remove the message, because a lot of people are used to their personal iPhones being secure and private and they need to be informed when that's not the case.

If they're issued a work phone, they may assume that the security and privacy are just as good as their own iPhone, not expecting that their boss can watch what they do. If they let an untrustworthy acquaintance use their personal iPhone, they may have no idea that it's even possible for the acquaintance to take a few minutes to begin managing the phone and then spying on them later.

Imagine if the boss or the untrustworthy acquaintance could just turn off the warning right after beginning to manage the phone. The user of the phone would then be kept in the dark about potential spying.

There's no easy way for an iPhone to distinguish between a spy disabling the message and the user disabling the message, so there's no easy way to allow for what you want while still ensuring users receive that vital information.

SFGate says essentially the same thing as far as its purpose being to inform users of possible spying.

Removing the management profile

Someone else mentioned how to remove the management profile from the phone. That has some potential issues:

• Your boss may not want you to remove the profile, which may lead to undesired consequences like being fired
• You may lose access to any resources the profile allows you to access
• You may start sending things unprotected directly over the Internet rather than through the VPN your profile sets up for you

Why the message probably can't be removed

As far as leaving the profile there, it's very likely that you can't remove the message because a lot of people are used to their personal iPhones being secure and private and they need to be informed when their privacy may be at stake because they may be being watched.

If they're issued a work phone, they may incorrectly assume that the security and privacy are just as good as their own iPhone. 

If they let an untrustworthy acquaintance use their personal iPhone, they may have no idea that it's even possible for the acquaintance to take a few minutes to begin managing the phone and to then spy on them later.

It's very likely that you can't remove the message.

Imagine if it worked the other way. Most people assume that work-issued iPhones are just like their own iPhone that they've grown familiar with, with all the security and privacy that entails. Most people also assume that their personal iPhones aren't broken into by untrustworthy acquaintances who set up the iPhone to be managed by them.

The message you're complaining about warns the user that the iPhone may be monitored or controlled by someone else. Imagine if that someone else could just disable the message right after beginning to manage the iPhone. The company or untrustworthy acquaintance could then spy on an unwitting user.

There's no easy way for an iPhone to distinguish between a spy disabling the message and the user disabling the message, so there's no easy way to allow for what you want while still properly warning users.
