There are all sorts of ways for AWS to raise prices without explicitly raising the price for an r7g.x64:
1) Starting charging legacy fees like the MySQL 5.7 fees
2) Start charging for hits, IO, etc
3) Tier out fees like with Aurora IO optimized to increase revenue
4) Push support levers
5) Stop reducing prices for older instance models
