Reckless to oneself and to others

Connecting to other peoples' PC in the way someone can now, without needing to ask the PC owner for permission, while Windows and other operating systems indicate that the PC owner/user is offline, and the PC owner/user thinks that no other person is connected to his or her PC, is reackless not only to the PC owner/user but also to the people who connect to other peoples' PCs .

And it is even more reckless by PC makers, operating system makers and authorities to allow people to this against other people.

It is like making cars but no rule and no law, and having no law enforcement, for what side of a two direction road to drive on.
