Why did the UK change from round pin to square pin plugs?

The sensible thing is to fit them with a fuse. Like all decent makes have. Then you can daisy chain them to your heart's content.

fuses don't remove the risk of what BS 1363-3 calls "undue strains on fixed socket-outlets" from the weight of multiple adaptors plus plugs and cords

Also does not help of all those extra contacts push the earth loop impedance high enough that you can no longer meet the required disconnect times in the event of a fault.

Then Darwin's law will take care of it.

No, that hardly ever kills anyone.

Same with too many adaptors, then. ;-)
