Another compelling reason is to avoid actively contributing to their ad ecosystem, which is ultimately paid for by the users and businesses that (have to) rely on the products because they are the biggest player in the market. One of many examples is how Google pushes for advertisers to bid on their own keywords, so you have the same result as the first ad and organic page. Is that really necessary? I'd rather get a discount or better service than click on an ad, performance marketing makes companies think otherwise because it's more difficult to measure.
