The “you wouldn’t download a car” statement is made against personal cases of piracy, which got rightfully clowned upon. It obviously doesn’t work at all when you use its ridiculousness to defend big ass corporations that tries to profit from so many of the stuff they “downloaded”.
Besides, it is not “theft”. It is “plagiarism”. And I’m glad to see that people that tries to defend these plagiarism machines that are attempted to be humanised and inflated to something they can never be, gets clowned. It warms my heart.
