Earlier quoted context omitted.
This seems to be overstating Apple’s position as neutral here, they are actively hostile to jailbreakers, and Apple will try to stop you any way they can.
Jailbreaking, by definition, is using exploits and vulnerabilities in the security of the device to bypass said security. Of course Apple is going to try and stop that. If they didn't, they'd be admitting that they don't care about the security of their devices which is a major factor in why people and companies buy their devices.
At the software layer? It's been litigated on more than one occasion that a company can't sue people to prevent jailbreaking their own devices.
