Most annoying about these kinds of situations is that the company likely hasn't even lost the data, but has simply removed your ability to access it. It's probably still being used to profile and profit off you, but good luck being able to use it yourself. I'm almost certain that this is the case with my Google search history, for example, where anything over a few years old has become quite difficult to access (entries that used to have very granular data about my browsing now simply list a domain), but I find it incredibly hard to believe that it's been completely discarded.

We desperately need modernized data rights and regulations. Companies can afford it.
