I literally moved away from Namecheap when they did a UI redesign many years ago. Their old control panel was ugly but functional. Their new one looked much more "modern", but was way less information dense, and they introduced jank and made stuff take more clicks and hid stuff behind collapsed-by-default menus iirc.
They also made their billing details UI no longer accept the letter "ø". The billing details UI which made clear the importance of making sure the name you enter matches the name on the card. And the name on my card happens to contain an "ø". That doesn't exactly instil confidence.
