The crypto key is what you are describing, not the pre-shared key the user uses.
The failure to communicate isn't our misunderstanding of the technological terminology, but your inability to put the technical terminology aside and listen to others.
And nobody was talking about what is "transmitted" so unclear what that has to do with whether the PSK you enter on the "passphrase" space on the router is a [PS]Key, or a passphrase. It's both. The terms are used interchangeably for that setting. And yes, that's confusing as "key" is used elsewhere for a different purpose. But that doesn't make your car-key not a key because it doesn't look like your house key.
Chicago's move is rational. It placed a use tax on entertainment, then argued that streaming entertainment is entertainment, not a "purchase" (which would fall under a different use tax). They are 100% correct, and the move is 100% legal and consistent with existing law and rulings. It's just that Use Taxes in general are silly and ignored. They only work when the state claims a nexus and converts it to a sales tax.
Personally I think 9% is outrageous. It had better come with a set of Monster network cables
9% is high, but not the highest. There are places with higher, and I'm not sure in that graphic whether they count hotel taxes and other such surcharges as "sales tax" and that's more like this one is aiming, as an "entertainment tax".
Use taxes don't depend on the service purchased being local. Note, Texas law prevents Tesla from selling a California Tesla in Texas across state lines, as well as "use taxes" being supported in court many times.
Or more specifically, Netflix content travels over Chicago right-of-way.
People who object to racism pointed out claim there is no such thing, even when it's pointed out. The Charleston shootings weren't about race, but were about a single mentally ill person with no ties to race.
One of the problems is that cameras are racist. The default settings work for me as a pale white person, but don't work for a dark person.
