Wasn&#x27;t that the consensus was that many countries (especially after WW1, and WW2) adopted different plugs to control the import of appliances? When plugs weren&#x27;t easily replaceable with kettle type cables and where you couldn&#x27;t just buy a plug in any home depot and change it yourself it seemed like it was a very good tactic to restrict the grey&#x2F;black import market.
