Not to be that guy, but the USB-C specification requires an extraction force of 8–20 N for a new connector, measured on the sixth unplugging cycle after five conditioning cycles. After 10,000 insertion/removal cycles, the permitted range is 6–20 N.

Equivalent hanging mass:

  8 N is 0.82 kg  
  20 N is 2.04 kg  
  

So the problem you have is likely one of your manufacturer not producing equipment suitable to pass the USB-C spec.

As an aside, the specified extraction force for USB A is:

  10 N minimum when new  
  8 N minimum after durability cycling  
  

So pretty much the same, in some cases even less.

I don't have problems with USB-C connectors per se. I think HDMI is worse in terms of durability.
