All that said, Comcast Internet's business practices is outright awful - they lied to me multiple times about my plan and discounts. And you need Comcast to use Xfinity - it's very expensive otherwise.
I could tell a horror story from Verizon about a multi-thousand-dollar roaming bill from someone I knew, from Google about being completely locked out of a phone number forever from another person, and lots of others.
Pick your liability.
On the whole, I found the risk of data theft from T-Mobile to be the lesser of the evils.

Tmobile is also widely considered to be the worst of the 3 US mobile networks (Verizon is considered to have the best coverage, then ATT, then Tmobile). Their pricing reflects that too, as Verizon is the most expensive, then ATT, then Tmobile.

I really hope TMO takes security seriously going forward.
My wife's immediate family is 9 adults, 6 of whom are all on the same cell plan because it's cheap and convenient for everyone involved. If everyone gets along, there's not a whole lot of downside here.
These days, access to your phone number basically constitutes verification and authorization from you for many things, including transfers of money.
I control the phone lines for myself, my wife, my mom, one of my cousins, and my sister. But I would not give someone other than my wife control of mine or my wife's phone number, no matter how much I trust them.
>If everyone gets along, there's not a whole lot of downside here.
Everyone always gets along, until they do not.
Like, you just provided the counter-example to your own point while making your point.
The billing is so consistent I just get a check every year from each person. I pay for my parents' lines. And my sis/BIL pay for theirs in one check. I round up a few $ for admin fees.
A completely fantastic deal for the everyone. Would not have been possible with Verizon or ATT as their bills had so many gotchas and varied every month.
