I've never seen AWS actively try to trick people into spending more money. I've seen Premium Support, product service teams, solutions architects, and account managers all suggest not to use AWS services if it doesn't fit the customer usecase. I've personally recommended non-AWS options for customers who are trying to fit a square peg into a round hole.
Can the billing console be better? Yes. But AWS isn't trying to trick anyone into anything. The console, while it has its troubles, doesn't have dark patterns and pricing is transparent. You pay for what you use, and prices have never decreased.
Hell, I know of a specific service that was priced poorly (meaning it wasn't profitable for AWS). Instead of raising prices, AWS ate its hat while rewriting the entire service from scratch to give it better offerings and make it cheaper (both for AWS and customers).
