What do you think the difference between a pop rivet and a blind rivet is? There are different types of blind rivet fastening systems with different properties, but the words are absolutely used interchangeably. Also, blind rivets are used extensively in automotive applications. I do think this fix looks quite shoddy in general, but I don't think a bolt/nut would be a better solution in that location.
