Answer:
It is impossible to know for certain what Beethoven would feel about the use of his music in modern advertising. However, considering that Beethoven was known to be deeply passionate about his music and its role in society, it is likely that he would have mixed feelings about it being used in commercial advertisements. On one hand, he may have been pleased that his music was reaching such a wide audience, but on the other hand, he may have been upset that the music was being used to sell products, rather than being appreciated for its artistic value. Ultimately, it is a matter of personal interpretation and speculation.
