It should be deleted, I can’t speak for a non legal behavior of the companies, but legally they must do it, if asked. Anyway I won’t put sensitive info on remote cloud owned by xyz. I was speaking for normal cloud content, like photos or simply documents.
For some anecdata on illegal behavior, Atlassian denied my data deletion request on the basis that they're legally allowed to choose to use logins as a proof of identity (since without some kind of proof anyone could prank delete anyone else's data) and since they'd given away my account the day before I thus couldn't login to prove that it was my data, despite having otherwise valid credentials and whatever other proof of identity they might need.
