That's just one reason why I don't use smartphones.
That, and the classic security/usability-tradeoff, render your implied suggestion somewhat obsolete, no? Sorry if I'm missing something.
Someone then argued "thats why I don't have smartphone", to which I responded that not having a smartphone doesn't affect the aforementioned conflict. So unless I'm missing something here, you just went entirely off topic.
Regardless: I'm european, so I'm somewhat confident that my ISP doesn't sell my data due to GDPR; Americas lack of consumer protection isn't really my business, nor should it be deemed 'the standard', as it isn't just that.
It was basically an emotional response to the idea.
I suppose that at least, not having a smartphone, I'm not sharing stuff about others. Except for the number, which is already ~widely known. But I wasn't thinking that when I wrote the comment.
But at least I'm not tracked so readily.
Also, I don't care so much about my meatspace name and email. There's absolutely nothing interesting about me in meatspace.
I'm not sure what I'd do if I actually needed a smartphone. Maybe I'd go with a PinePhone, with cellular and WiFi turned off, and external routers. Hopefully someone will come out with small routers.
But on the other hand, maybe that would attract too much attention. So perhaps a basic smartphone would be better.
