They dont't want AWS royalties. They wanna be able to command higher margins. Since AWS has lower costs and prices, Redis can't compete with good margins. The royalties are just a way to increase AWS costs, so that they raise their prices and give Redis the ability to keep high prices and margins, while still remaining attractive to customers (which don't have a cheaper choice anymore).
They want to make ludicrous profits on the software others have built for them.
There's nothing wrong with making money and being profitable. But they have to justify investments taken with greed. This license change is motivated by greed, not by "making money" fairly.
