An example would be check24. It's just a random German comparison webservice. However, as they produce unbelievable disturbing video ads I can't block, I passionately hate them.
This is enough for them in the long run.
That said, I'm still not buying anything Sony -- almost fifteen years after their rootkit scandal.

Edit: I found this part even a bit amusing: "As of 2013, the Nestlé boycott is coordinated by the International Nestlé Boycott Committee"
But maybe we are talking about different areas of daily life or I am grossly underestimating the power of ads on me. So feel free to present examples or evidence to the contrary.
Edit: There is also of course the large fraction of ads that simply cannot influence me in any way, because I simply don't buy products from those categories (lotteries, terrible AAA games, etc.).
I must be the exception then, because seeing these ads makes me actively avoid these brands in the future simply out of spite.
Sure they lose targeting, but physical media has existed for years based on ad revenue from companies that paid them directly for advertising. Even the tiniest local and university newspapers have gotten by with free distribution and paid ads for as long as I can remember.
The truth is that advertising works on almost everybody.
