Yes. The USB-C locking mechanism is terrible.
That said, must admit I've yet to see one of those connectors fail though after heavy use.
Mini-USB was worse overall regarding locking. Micro-USB only marginally better, but too flimsy for my taste.
It is not so much that the connector itself fails but they most often break off the PCB unless heavily mechanically restrained (e.g. by a clamshell-like case like in a smartphone). That was a problem with micro USB too to a degree.
Re locking - mini USB I have never really seen to wear out but a typical mini USB on a camera or USB hub typically doesn't see that many cycles.
Micro USB on the other hand is terrible. Due to where these are used and the shape of the connector it will stop retaining the cable after a while (even a new cable). The shape is not obvious during insertion (one has to look really carefully) and it is possible to try to insert the connector in the wrong orientation, deforming/bending the shell in the process. It is probably also due to the fact that these connectors are used as charging connectors for phones, tablets and similar devices where there are tons of plug/unplug cycles, so they inevitably end up damaged after a while. It is a very flimsy connector for such use.
Hopefully USB C is going to be better because of the "no wrong orientation" (so no chance to deform the shell unless doing something really stupid) but the way most of these need to be mechanically mounted and the PCB routing issues make it a royal pain in the backside.
However one neat thing that was done during USB-C standardisation was to also standardise screw-locked versions of the connectors.

Haven't seen these before, nice!
