Yes, especially as the company could just implement a button "Delete your data" on their website. An automated task initiated by the user. No work for them.

Companies could also make clear before any registration, on one page, which data they will ask for and later collect. If they were honest. Then the user had a chance to opt out _before_ they have given any data to them.

Well, they are not honest, because what do they do instead? Page 1: "Please, your E-Mail". Page 2: "We also need your phone number (we may call you)". Page 3: "Great, nearly done. Now please, your address, your credit card, a fingerprint copy and a picture of your penis".

I am in favor of appending a zero to those 5.000 Euros.

It gets in the way of ever increasing profit. The most important thing ever.

Not allowing reckless disregard for the rights of people = literally fascism.
