Technically that could be a fallout. With the upcoming ePrivacy/GDPR in the EU, if you as a consumer sent a DNT header or disagree with being tracked, you can notify anyone doing so and they are under EU law required to delete your data and/or stop tracking you. If they don't... well the nearest consumer protection office will be interested and they'll probably then follow up with blocking the website EU wide. So in conclusion; yes this can be used against anyone who tracks you on the internet against your will since the EU law will make that illegal in the future and this law is a broadside against anyone trying to ignore EU law.
