An exception is for testing.
I use Firefox nightly and developer edition where I can. I think by installing a pre release version of Firefox I opted into telemetry. I’m volunteering for telemetry. However, I don’t consent to opt out tracking in the production version of Firefox or running nonsense marketing-driven “experiments”.
GDPR is the best thing to happen to the web since javascript.
EDIT: Corrected, thanks, colejohnson66
There’s also the fact that GDPR is a directive. Each state (nation) has to implement it in their own laws. So the EU itself can’t enforce it, only the member states.
[a]: The purpose of laws are not to be an “eye for an eye”, but to curb bad behavior (theoretically)
It's not. It's a "Regulation", a similar kind of legal act to a Directive, but comes into effect all on their own, across the whole of the EU. https://en.wikipedia.org/wiki/Regulation_(European_Union)
But there is a huge difference between usage tracking and usage tracking for ads. Usage tracking of the kind Microsoft engages in (outside of Bing and their ad focused usage tracking that is), is largely telemetry used to change their product.
Usage tracking for ads, however, is used to change your behavior both within the product and outside the product.
Usage tracking for ads is significantly more damaging to humans as individuals as well as societies.
