The instant cascading worldwide deletion upon closing or deleting a subscription sounds like a recipe for disaster. Why not mark it for deletion and delete say... a day or a week later?
Weekends and public holidays are a thing, plus it’s quite common for companies to shut down for 2 weeks over Christmas.
There’s a lot of opportunity for mistakes or malicious actions to happen at times that won’t be discovered for a while.
Because in case of a compromise/unauthorized access that's exactly what you don't want to happen
No, not really. That's pretty basic stuff. You would do well in reading up on the shared responsibility model. Customers are responsible for setting up their own infrastructure, and platform/service providers are only responsible for the services they manage. Even then, stuff like persisted data is still recoverable by design.
But you are absolutely responsible for the service you put together. This is a basic principle for around two decades. Infrastructure as code tools are pervasive and ubiquitous for over a decade.
Try experiencing it in person
Again this is the naive view
Again if someone compromises your accounts and everything is deleted instantly you'll be the one looking like a fool
I don't agree. What do you expect to happen when you explicitly delete your user account? Do you expect your systems to remain in operation for a week? That itself would be a major risk and liability, as your whole infrastructure would still be up even though you cut your access to it.
Also, isn't your whole infrastructure expected to be automatically deployed with IaC? The notable exception is data, which is already soft deleted and recoverable through customer support.
All in all, where do you expect the customer's responsibility to end and the cloud provider's to start? The shared responsibility model is covered by any intro course in no uncertain terms.
