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.
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.

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.
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.
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.

Everyone always gets along, until they do not.
Like, you just provided the counter-example to your own point while making your point.
