Thats the point.. Don't give a shit if they can. I'm sorry but I am a bit of a computer elitest. I don't think ISP's should be reponsible for blocking ports or making security decisions on the behalf of their users either, but if they start spewing malware all over the place, then they need to be banned. Proper usage and consequences, there is a secure way to do transactions, people just don't like security. In that case don't bitch about the consequences (not you, just people in general aren't willing to do what is necessary to secure themselves).
When people insist that things are done for them, restrictions get tighter on those of who DO know what we are doing. Companies start catering the lowest common denominator... case in point... Android and Apple walled gardens where you are no longer the admin of your own device. You aren't deemed smart enough to control your own security destiny so they take the functionality away.
Yes, I am a computing elitest. If people don't know what they are doing, then deal with the consequences.
