European Union Justice Commissioner Didier Reynders recently told German newspaper 'Welt am Sonntag' that the European Commission is aware of how annoying cookie consent banners have become...
We have the Do-Not-Track standard, enforcing its functionality by law would've been so useful.
Most cookie consent software has an option to respect DNT, but people/agencies just don't configure it, because they don't have to.
The dumb part is that most Cookie Banners do not actually adhere to the law. While I do see room for improvement in the law itself, those improvements will go unseen, too, if the law is not enforced.
Cookie banners would not be necessary if companies weren't trying to do shit with data, specifically personally-identifying data and personal-behavior data. If they were just running simple analytics over everyone without trying to do stuff like figure out my personal click paths and then associate that with mail address I typed into their newsletter form accidentally and then combine that with data from millions of other websites, there'd be no absolutely no need for cookie banners. The EU never said that all websites have to use blatantly non-compliant services from Google, Adobe, and tons of others.
This is not a failing of the GDPR. This is a failing of web designers, corporate marketing structures, and the legal system.
