I believe the only way for the author to succeed is to provide exactly what the visitors want. If there is an automatic video / audio, it is probably there because the majority of visitors like it. So probably, you are in the minority, but want to forbid something for the majority.

Honestly, I am quite scared by people, who so easily agree to ban or restrict things for the whole population, just to avoid those 3 seconds of a day, during which they may feel uncomfortable.
