>The question of ownership is interesting. If I buy a chair, it doesn't make a very good table, does that mean I don't own it?

A better comparison is buying a chair where the seller gets to aprove who sits and when.

Indeed, and think how much more secure this is for Grandma! What if a scammer comes over and wants to sit? Won't somebody please think of Grandma

Not really. My point is people don't even think they're buying a general purpose computer because they don't know what that is. They are buying a cloud terminal and it works as a cloud terminal. You might think of your smartphone as a computer, but you're wrong. So it's a chair and anyone can sit on it, it's just not a table. It never was.
