A lot of the problems with the original that were blamed on bad power supplies were probably issues with the Pi itself, to be fair. For example, as originally released connecting any USB keyboard or mouse would cause the onboard USB hub to fall over after a while due to a spec violation. There was a long list of supported and broken devices on the wiki, with the non-working ones being accused of drawing too much power, but in reality the problem affected every USB keyboard and mouse. When someone's Pi fell over despite using supposedly tested and working devices, guess what was blamed next? That's right, the power supply they were using. Inadequate power supplies became a handy scapegoat for every single Pi reliablility issue. (Eventually, some outside engineer with a USB analyzer got fed up enough to track down that issue. The Pi Foundation didn't spot it. They almost never do.)
