Hitler especially was actually making good progress until winter hit so you could almost even say that Russia took a calculated risk (even though I think it’s more of a “got lucky” situation).
It’s ridiculous and the worst part is that they’ll probably get away with it too, same as Netflix. My family consists of 3 households sharing the same account, with these changes that would mean €6 a month extra on the first account + having to create a second account which will also be like €10 a month or something.
