I really don’t think they should be dictating how companies must design their products.

Like say telling to automakers they must include this design feature called seat belt and this another design feature called airbag? Also EU isn’t dictating anything about the design. They are giving regulation on minimum technical features. How to design within that minimal technical requirement is free for the maker to decide. Just as say there is minimum technical regulation about safety of electric appliances in general.

Again poor, poor companies being told by the regulation they can’t use their favourite “design feature” of "exposed uninsulated power wirings " on their products.

Regulations have existed and will exist. Companies operate at the please of society offering them a market to operate in. Offering such things as contracts needing to be honored, people not just being allowed to steal their property, enjoying the protected relative piece of national military keeping the mongol horde away and so on. In exchange the businesses shall play by the rules society sets.

This matter was decided by the duly elected representatives of the EU citizenry (directly as the European Parliament and more indirectly the national democratically elected governments in the Council. Well except maybe governments of Hungary and Poland… … …). This is the will of the European society, so this stands.
