I did read your whole post.  And that's fantastic you said you would replace it.  But you ALSO did say, that people don't understand the value of unlimited data.  I assure you, that the vast majority of us on a website such as this, fully understand how awesome unlimited data is.  
The things you circled in no way change what you said where I quoted, or what my response was.  I agree with you that he should exchange it.  But I don't care how "valuable" unlimited data is when my loved ones are at risk.  Any risk.  If I can do anything in my financial or physical capabilities to lower any risk of danger, I'll do it.  Even if it's 0.1% of a chance.
