Two points.
Avoiding the ads via the FF button is getting harder because some channels vary the lengths of the ad breaks and, misleadingly, show the station logo and livery midway through, making you think they are finished. Maybe advertisers have to pay extra for ads placed after the false alarm.
Secondly, if an ad really annoys or disgusts you, it is still permitted to boycott the product. If ads became counter-productive they would have to think again about material that offends viewers in their own homes.
