Logo would be covered by trademark, not copyright, but… yes, abusing it is actionable if the trademark holders want to pursue the matter.
As I said in the other thread, anyone who would write that nonsense into their sales contract is planning on having a significant number of disgruntled customers, which tells you all you need to know. This just confirms it.
BTW, aesthetic design of physical objects is yet a third category: “design patents” are the equivalent of copyright for that domain. If you see “Reg. US Pat. Off.” (registered US patent office) rather than “patented”, that’s almost certainly a design patent rather than a technical one. My father liked to tell stories about the great inventor, Regus Patoff…
