That's stealing. It's up to you ultimately.
Is it stealing when you allow your wife to watch the cable TV subscription that is only in your name? I'm sure you and her both have paid for it seperatley, right?
Same with power.....
Same with water..... surely you pay for and use seperate water meters for each member of the family right.
Every phone I have on my family plan uses the same Gmail account as the main account. (MyFamilyname)@Gmail.com and then we each have our
specificname@Gmail.com on our individual phones.
As the main phone account, I control what apps go on the phones and I can see what apps are downloaded through Google.
