Why are hardware companies keeping customers information after they have successfully delivered their products?
And how do you propose handling the replacement of these HW-devices during the warranty period, for instance, in the event of a HW_manufacturing defect or a HW-device failing prematurely?
Isn't this the reason why scammers are able to get their hands on people's addresses and emails?
This happens due to an inadequate level of protection when such data is stored. Why does no one encrypt personal data while it is being stored?
Most especially crypto hardware wallets that claimed to be airgapped, what business do they have with keeping customers addresses after many months have passed? Why can't they get rid of every information once delivery is been made?
Because otherwise, some clever person could send them a broken HW-device to be replaced under warranty. The HW-manufacturer is trying to protect itself. But I also don’t understand why they couldn’t anonymize personal data (or instance, by assigning a unique alphanumeric identifier that confirms you are a customer) and use that instead. Naturally, this would also involve significantly shortening the retention period for customer's personal information.
The most successful year yet for hacking HW-manufacturers is not over. Which company will be next? Perhaps it’s time for them to join forces and collectively develop methods for the anonymous delivery of HW-devices, without the need to collect and store personal data?
Why do you keep any of your information on any website? Why have social media or accounts on online store? Delete the account after each order, be the first to show an example! Grin People don't delete stuff like this and they don't want to, so magically they expect companies to act differently.. when companies are made from these same people that don't do it in their personal lives?
Okay. I guess I’ll go ahead and
delete my passport and all my other documents, then.

Are you serious? And how is a buyer supposed to receive a package containing a HW-device? In case you didn’t know, no postal service will hand over a package without supporting identification documents.
These data leaks are bad, but you need to be certain that everyone is responsible. Why did customers give their real info and not use a PO box? There are many things that a user could do if they cared..
Because it’s not available everywhere!
There is no justification for why customers should have given incorrect details, not everyone knows how to cut corners, if the company required you to submit and email or some personal information that are sensitive, people usually give correct details
To receive the parcel they paid for.
