For example, there's a lock on the Annotations demo. This makes me think it's unavailable. But clicking on it shows both the code and the output! That's because the demo has been unlocked since 5 people have sponsored it. If it's been unlocked, why is there a lock icon?
> More confusing, a lot of the locked demos had been unlocked by sponsors, so clicking on them worked! So why was the lock still there?
I didn't understand this part. Are you seeing locks on the first three demos?
