The consequences only highlight the problem. We're currently in the first stage in a transition towards allowing the end user to express their wishes about tracking which then companies need to respect.
It only shows how disrespectful almost all companies are by attempting to shape the end users opinion on this law by attacking them with dark patterns.
If France is now expecting companies to equalize the opt-in and the opt-out behavior, they're essentially attacking these dark patterns, which is very welcome by almost all end users.
I hope that there will come a point in time when I can go into the settings of my browser, tell it what the default behavior (answer) should be and possibly even express interests in certain ad categories to whitelist them, like "biking". It would be a granular "Do Not Track" option which must be respected by the website.
