I wish my main and inspiring takeaway here would be that we can fight them and win.
However, I was in no control here. The fact this resonated with a lot of people causing an internet wide uproar was nice, but Oracle's legal time could've decided to not care.
Are they taking the wind out of our sails by reinstating my account? Is this their way of admitting and undoing an honest mistake? Would this have happened if I never complained publicly about it, or was my private GDPR request what did the magic here?
I cannot tell you. All I can say is that your account and all your data still exists on Oracle's servers even over a week after your account has been “irreversibly” wiped. Keep that in mind the next time support tells you there's nothing they can do.
