I guess the $40 went to pay the folks who answered a lot of phone calls.
Now if no tests need to be uploaded, stop the $40 or cut back to $20 for just the other questions.
All a bit of a game too.
BTW if flying from Canada to Europe, they now say no testing needed, but if your plane goes to a US city and you change plane, then the rule changes.
FYI
A very well know You Tuber tells the story of how he is glad he got a test to get to Amsterdam because his flights changed to include a stop in US thereby making a test necessary.
Boy keeping up with all the rules is a job in itself.
