For me personally, when those data protection laws where implemented, seeing the extent of the market for user tracking was a shock to me. The respect that I lost for actually quite a lot of companies as a consequence has informed some purchasing decisions. And I don’t think anybody would mind those banners if the opt-out option you want to click is reachable with a single, easily visible button.
Edit: Responses suggest that the GDPR already contains something to that effect. Glad to know. If that’s true, then I guess it’s time for court cases to sort this out.
