The Pi is an amazing device. Sure. But the devs should have held off and provided more testing before releasing into the Wild. How was the USB charging thing even missed? We’re they only testing with their official chargers? That’s mystifying...
No, it's pragmatic. Have you any idea just how many different USB C charges there are in existance? it's impractical in terms of both time and expense to test anything more than a tiny subset of them.
Speaking as someone with significant experience in QA and software testing, you can never test everything prior to release. There are always things that crop up in the wild. The best you can do is mitigate those issues and add them to the test plan for the next release.
Bullshit. They admit the issue and their fault.
They will have to release a new version of the pi4 to fix that.

Please mind you language.
Whether or not RPT/RPF have admitted the issue (they have), and whether or not there will be a future board revision to address it (it has been stated that there will be) does not make my comments invlaid (or B*sh?t)
That this was missed is an error in a complex process. Writing test plans is not straight forward and as for beta testers, most of those won't be experience test/QA engineers (I am but I wasnt' a beta tester) and will have used the equipment they were given. Without hindsight, if you were sent a 4B, associated cable and an official power supply would you have plugged in a random USB C charger that you just happened to have lying around?
It is not practical to expect RPT/RPF (or any other company) to have tested every possible combination of their device and all third party devices.
To illustrate my point about designing test cases/test plans I'm going to set you a achallenge:
Give me three test cases for the piece of software specified as follows:
Program will repeatedly prompt for a number until it receives a "*". It will then calculate and display the average of the numbers entered.
Please, can no one jump in before kyliael has responded.
Oh, and as I said in another thread, you need to grow up, gain some maturity, and calm down. And learn a little more about where yo fit in the world and how things actually work.
