Because it is bad. In any connection there are springs that keep the tension, which will eventually wear out. They can either be on the cheap replaceable cable, or in the receptacle that is hardwired into your expensive device.
> Why Micro types offer better durability? Accomplished by moving leaf-spring from the PCB receptacle to plug, the most-stressed part is now on the cable side of the connection. Inexpensive cable bears most wear instead of the µUSB device.
Definitely had an iPhone where the port was worn out and getting it to connect was difficult.

This is why, in part, USB Mini was replaced by USB Micro. ( https://electronics.stackexchange.com/questions/18552/why-wa... )
