Apple had plenty of time to get this sorted. There’s no reason this couldn’t have been done through stores or via mail and online.
This is categorically untrue. The lockdown was enforced literally a few days ago with it being presented to the parliament on Wednesday. So no, they didn’t have “plenty” of time. A change in operation at such a huge scale is not a piece of cake.
There must be a reason why they force people to go into a store as not being able to buy online just by clicking a couple of buttons is a huge barrier to selling an item and a company like Apple is very well aware of that.
You can choose not to upgrade and yes the reasons are obvious. I’m on the same boat but blaming Apple is not the way to go about it IMHO.
