However, they do indeed feel quite a lot more fragile. USB-A is an absolute tank, and I regularly just haphazardly plug it in without paying much attention to it, knowing that I'm not going to damage it. With USB-C I'm always a bit careful about not putting too much strain on the connector - especially as most connectors are rather long and act like a lever!
I can totally see myself breaking off USB-C ports because I forget to unplug the cable to my docking station. With USB-A, I pretty much expect to break the cable first.
It might seem that way, but the port supposedly breaks more easily than the cable in USB-A, since the A port contains springs (which will eventually get worn out and can be bent).
Anecdotally, I've seen tons of broken A ports with exactly that failure in airplanes, buses, and other places with public USB charging ports that people don't treat particularly nicely.
The leverage of C plugs does seem scary, but I have yet to encounter a broken port – fingers crossed!
