Your article does not support the idea of the cost having doubled - hence (I assume) the suggestion of clickbait.

In order to show that the pricing has doubled, you'd need to show an increase in actual monetary cost to a customer, not that the margins have changed. The table of prices has no historical data, making change impossible to determine.

I'm sympathetic to the idea that RDS is overpriced, but can't say I'm convinced by this article alone.
