1) Because the people who contributed to the development of those other processes received fair market value for their work (for the most part). The vast majority of contributors to the process that made this logo have not been compensated for their work. This differential can lead to an ethical judgement about the process, which can transitively be applied to the logo made with the process, and the restaurant as a whole.

2) Some automated processes lower the quality of outcomes. Microwaving food might be a faster/cheaper way to cook, but customers might criticize the results.

3) Some processes can be viewed as having lower value compared to others, independent of result quality. This is particularly common in the art and service industries, for which the logo of a restaurant is very much at the intersection.
