No, there's nothing to praise here.
When I delete all my repositories by hand, one by one, I expect to not find a joke in that email about how "this email is sent to you because you have an active repository on Gitlab".
When I delete an account on Gitlab I expect to be deleted from all further mailings (especially ones I never subscribed separately to), yet I got this email today. How many more places do I have to delete my information from to finally be rid of Gitlab?
How many more third-party companies Gitlab shared my data with at this point? Because that they do have it, there's no question about it - after all I just got this email.
