Or when they decided to wipe people's Hotmail accounts. Now some random person has my original hotmail that I had since the 90s through to the 2010s... Presumably, this person now indirectly has a ton of my original accounts for different services I can no longer access... thanks Microsoft.

I'm so happy I managed to transfer everything important over to my own domain before anything like that happened. I still have my old Hotmail and Gmail, and while nothing important shows up there, there's still a trickle of non-spam email coming in there, even after 5 and 10 years since I transferred everything I could remember at the time.
