As some others have pointed out, you have missed the bigger problem completely.
Live - neutral clerance is, if not safe and up to regulations, at least... quite OKish, when compared to the massively horrible and immediately lethally dangerous lack of clearance between primary and secondary (through the secondary side main copper pour). (I'm assuming that the low voltage side ends up being touchable by the end user, through connectors or otherwise. If the complete product is fully physically isolated, please ignore this post.)
Exact requirements vary per legislation, but primary-secondary creepage and clearance requirements are always bigger than the live-neutral limits, and for a good reason: arcing between L and N only tends to cause increased risk of fire, whereas between the live (FYI: neutral wire is always treated as live as well) and the protected side, the result is not only a risk of fire, but an imminent, invisible electrocution death trap as well.
Eyeballing from the image, primary-secondary clearance seems way below 1mm if not 0.5mm - reason for immediate product recall due to being a massive death trap.
You tend to see beginner issues like this on Western products designed by amateurs, often accompanied with a marketing assumption of high quality. Chinese power supplies get a lot of attention for doing this sort of thing, but they typically have better idea about what they are doing.
