All my data has been leaked so often now by various companies, including my W2 when a past employer got spear phished. Meanwhile I have a really good contract with T-Mobile and been very happy with the service. Both in terms of connectivity and in-store service. While I'm upset about this, I'm not gonna go through the hassle of moving to a different service provider, all of whom have bad reputations anyways.

Pretty much this. I cant seem to find it now but I read a study late last year that data breaches/hacks have almost no impact to the share price, no impact on customer base and consequently no impact to the leadership of a company. Thus, leadership is less likely to invest in security and privacy of their users.
