What kind of "enterprise applications" exactly ?

In other words: a direct backdoor for the "provider", who can do
anything he wants remotely on the user's machine, w/o the user having
a chance of seeing what's actually going on ?

Seriously ?!

In some of your previous mails (*1) you indicate that it sends some
diagnostics information (eg. "dock is not working"). WTH does that
have to be "proprietary", IOW: encrypted = kept secret from the owner ?

If I *own* such a device, this is some information, I *need* to know,
I *deserve* to know, and it is *my* data, as it's a state of *my*
device. And that's some kind of information that *nobody* else has
any business with that. Period.

Seems you folks (Google) still didn't learn the fundamental difference
between ownership and just a license to use. And the recent multi
billion fines against Google still haven't been enough, so I'm looking
forward Mrs. Vestager's next strikes.

I'd like to remind you of the famous words of JR. Oppenheimer:
""Now I am become Death, the destroyer of worlds."
(quoted from the Bhagavad Gita, when he recognized the desatreous
consequences of his work)
