Having worked at these companies and those like it, there's a lot to unpack in this law. The short version is, they have to delete data "about you", not data that was generated by you. Business records, such as receipts, are allowed to can be kept. They just delete your name and phone number, your photos and videos, and documents that were visible to you, but all of the actually useful tracking information is encoded into "Anonymized rows". It's bullshit and everyone knows it except the legislators writing the laws. That said, there's also a clever but effective workaround to all that redundancy - They store all your documents and photos encrypted with a key that's unique per user. When you request all your data, they delete the key - It's much easier for them to completely and quickly purge all that as a singular key, and clean up the files later. It's not a cop-out, because there's no effective way to get at your data once the key has been deleted. Those systems still have backups, but with much shorter lifetimes and explicit audit logs.
