Just a question - if you are dependent upon the hosts network manager does this compromise security ?

Would it defy VPN management ?
Ubuntu does exactly that:
I have discovered that VPN breaks inside Ubuntu Touch unless you wrap the system inside a cocoon.
This is probably why the Ubuntu Touch system has -zero- VPN solutions available for installation.
Fixable - but the hazards are very real.

I am inside a rising storm of governmental internet blockage
and not having immediate direct control of what my connection is doing is,
right now - very annoying, later - possibly very dangerous.

Having some stray javascript dialing home to somewhere local authorities
regard as a 'national security issue' could cost you your head in the wrong jurisdictions.
For some oblivious Android user this is not a problem to plead ignorance about.
For people like us carrying modified communications gear
the glimmering stares of suspicion may accept no amount of reasoning.

[side note - back in the early 90's I recall getting security called on me for simply showing up in a Toshiba plant to ask how to wire my brand new mobile handset for rs232 so I could hack faxes over it. The Toshiba management grilled me for over an hour in a locked room. Eventually they calmed down and let me go, but they were not interested in me being able to hack the device they sold me. It was a both a local government issue and a corporate security issue.
Of course they made it onto my do-not-buy list.]
