There's totally no EU law forcing companies to delete stuff you bought.

No other online store is doing this. The only one that comes close afaik is Ubisoft (who couldve guessed), but only if you own zero games on that account.

They are required to delete certain data about you if its no longer necessary for their service, but not everything, especially since you have an ongoing contract with them. They either couldn't be bothered to only delete parts of data they consider useless already and instead chose to just wipe everything, or that's their way of malicious compliance.

Under the GDPR, every organisation must:

Define how long each category of personal data is stored Justify each retention period with a legal or operational basis Ensure data is deleted or anonymised once the purpose ends Document all retention rules in a clear and accessible format Apply retention rules consistently across all data systems Ensure third-party processors comply with the organisation’s retention instructions They can define their own reasonable terms. Sony chooses to delete that stuff.
