Ads don't usually worsen the image I have of the product, unless they are bad or clearly misleading and dishonest.
I do avoid certain services though, because they have ads. My country's two biggest commercial TV channels have free services on the web where you can watch plenty of interesting stuff, from a show you missed to all kinds of behind-the-scenes and other extra stuff. I tend to keep away from them or watch only something I really want because there are few second unskippable commercials before most videos. The equivalent-of-BBC has a much better similar service with generally more interesting content, in addition to no ads at all, so I use only that.
The exact same goes for radio channels. I always prefer the non-commercial channels.
