GameFreak 2003: "You can store more Pokemon than before on your GameCube and still have full ownership over them thanks to Pokemon Box."

GameFreak 2013: "Here's a revolutionary new product: store more Pokemon on our computer, I mean The Cloud, at the sacrifice your ownership over them for an annual fee thanks to Pokemon Bank."

GameFreak 2020: "Yea it's the exact same product as before, but this time you can store all your Pokemon on our computer, I mean The Cloud, have no ownership over them anymore, because WE decide in which games they are usable now TEEHEE!! Oh yea, and you will pay us monthly for that thanks to Pokemon Home."

Nowadays, the LESS you pay, the better off you are!
But this is what "you'll own nothing and be happy" by Satan Klaus ultimately means; you pay for stuff you don't have.
