That's a very conspiratorial view of the world in a forum that dissects these devices and delves into the minutiae of the components used and their performance. A power supply is a component of the solution. Certified products are designed better and use higher quality components in order to pass certification tests. Having designed and built systems to comply with safety standards I know that they force higher quality components and manufacturing processes. An uncertified device is an unknown quantity.Also, I suspect that some posts here about the safety of these power bricks are made simply to undermine these Class D amps coming from China. Add a little fear to the conversations where possible to sow doubt about these products.
These all represent risks. The overall goal of safety standards is to reduce risks, especially unnecessary risks that we know how to minimize. These standards and electrical codes are the reason why all those perils that you describe have not done more damage. The systems are designed to be resilient in the face of multiple failures. I find it odd to point to the overall robustness of a system that has been regulated for many decades and suggest that the standards have little to do with it. We would hope that these electrical systems were within code when installed. Just because we know better now, doesn't mean we knew nothing then and it doesn't mean we won't know even better in the future. We should be promoting safety regulations not undermining them.Many thousands of homes in the US are old enough so that their entire electrical systems are out of date and out of code. There are plenty living in the US who still have knob and wire systems in the walls. There are millions of devices with old cords, cracked sockets, loose internal connections, etc. etc.. There are millions of internal wires running in houses that have been nicked, soaked, chewed on by squirrels, etc. Small Li-Ion units are plugged in by the literal millions. The failure rates are infinitesimally small for all of these gadgets.
Failure rates are small because of standards and vigilance in removing unsafe devices from the market.
By the way, according to the US Fire Administration, "The 2022 national estimates for residential building electrical malfunction fires and losses show that there were: 26,100 fires. 185 deaths. 850 injuries"
