Do you actually read the dozens of responses? Or are you just doing it to annoy people?

Yes, I read the responses and take action upon them. The last time I quit my bank account to move to a different bank.

Also, I'd recommend sending another request some time after quiting your contract with the company, just to make sure they give you a written guarantee that they deleted all data about you they don't _seriously have to_ maintain.

I intend to use it as well. Since I'm about to move, I wait until I have the new address. Yes, I'm interested what I will get in return.

I also consider it activism to keep companies aware of their responsibilities.

..and drive up the cost of goods and services.

Does anyone actually understand that this law will make things cost more?

Keeping my data private has costs associated with it? What a shocker!

Do you also argument against mandatory seatbelts? All they do is drive the cost of cars up. The justice system that works to enforce the laws brings the taxes up should we get rid of it too?

This guy being the equivalent of a car manufacturer in your analogy...

Maybe. But it's worth it.

I read them, and often I make decisions based on this — or can use it to convince e.g. my family to stop using payback (a discount scheme where a company logs all your purchases, even cash ones, and you get ~1% cashback).

Why do you think otherwise?
