USB-C mechanical design is flimsy and pathetic.

Easier than fixing the problem!  :D

I think this was discussed in another thread before.

The design may not be that robust, but it's not that bad a compromise actually. Can you think of a better design that would fit within the same volume? (Remember it's used in small products such as mobile phones...) If so, I think many people would be interested.

Regarding the PCB side, I personally would only consider SMD connectors that have mixed smd and through-hole pins. That's what I used in the only device I designed (so far) with an USB-C connector. They are significantly more stable mechanically-wise.

That said, I never had an USB-C connector failure so far with commercial devices, but I have with micro USB.

A lot of the complaints sound like a mismatch of expectations and a lack of comprehending the scope of design tradeoffs that have to happen for consumer electronics. 

USB is NOT an industrial connector.  It is NOT designed to be indestructable at any cost.  It's designed to cram a shitload of throughput and an impressive amount of power into the smallest possible space.  Small devices that demand tens of watts of power and gigabits of data sell, and so those parameters are worth prioritizing over a certain amount of ruggedness. 

If you think it's so bad, take a minute to understand the ACTUAL application requirements and then see if you can design something that better meets them.

Don't see the issue tbh - when was the last time anyone complained that inserting a polarised mains plug into a wall outlet was "a problem"? The 12th of never is when.

I don't know about you, but every. single. time. I plug in a rectangular connector I have to look at the connector, look at the socket and see if it's the right way round.  Whether it's a micro B, full size A, or DP, or even a ribbon cable.  Oftentimes it's in low light or sometimes in a place I can't see.  You don't have to be a woo woo visionary to see that if you can solve that problem by designing a connector with 180d symmetry the life-time cumulative ease of use improvement is HUGE.  Calling "cOnSuMeRs" stupid and lazy isn't the sign of an engineering genius it's the sign of a dick.
